Introduction
Actuality
Donbass Donetsk coal or pool is one of the largest mining areas in Europe and around the world, where for more than 200 years of industrial development produced over 8mlr.t bituminous coal and anthracite.
For Donetsk-Makeevka area, as for most of the Donbass, one of the main pollutants of the environment is the coal industry. In this regard, the most important is the study of the features of environmental pollution as a result of activity of the enterprises of the industry.
Peculiarity Donbass coal is increased concentration in them of some heavy metals and toxic elements - mercury, arsenic, sulfur, molybdenum, beryllium. Individual brands coals contain higher concentrations as lithium, thallium, scandium and other chemical elements. Significant excess Clarks sedimentary rocks and coals fixed elements I-III Hazard Class: Sb, Pb, V, Cd, Zn, Mo, Li [ 1 ].
Today, the main factors contributing to the spread of particular pollutants, are not only the composition of coals and specificity of the process, but also landscapes of the study area. In landscape components at all levels are formed mechanical and geochemical barriers, where pollutants are concentrated biosphere elements and substances. Study of features of distribution of pollutants in the components of the landscape is an important task in the study area.

Review and analysis of the topic
Research close to the subject of this paper highlights a number of publications.
Volkova TP and VV Falevich [ 2 ] analyzed the impact of coal mining enterprises in the condition of the environment on the example of a mine field mine "Lidievka." Izuchen0 statistically the spatial distribution of elements in soils, conclusions about areas of maximum accumulation of elements.
In "Assessing the impact of a coal mine on the environment» [ 3 ] examined the causes of the ecological crisis on the ground, as a result of the industrialized world. The coal industry will inevitably adversely affect the environment, polluting and violating her. To solve this problem were identified promising clean technology, ecological processes and equipment.
Job "Evaluation negative impact on the nature of the mine» [ 4 ] is devoted to the study of the main sources of pollution of the environment and determine the influence of the activities of the neighborhood of the mine on the example of mine Zasyad'ko.
During studies of the effect of industrial objects observed a significant influence on the formation of halos landscape pollution. Geochemical studies of landscapes are widely used to assess the environmental pollution.
Basic ideas and landscape geochemistry provisions were formulated in a series of brilliant articles 40-50s B.B.Polynovym [ 5 ]. Under the terms of the migration of chemical elements BB Polynov identified three main elementary landscape: eluvial, superaqueous (surface) and subaqueous (underwater). Polynov showed that the migration of chemical elements connects the rocks, soil, living organisms, natural water and the atmosphere, that by studying this migration, we thus we reveal the substance of the relationship between these components of the landscape, we understand it as a whole.
Next this topic evolve in several editions of the textbook "Landscape Geochemistry» [ 6, 7, 8 ]. Were sformultrovany main concepts of science, based on the ideas of VI Vernadsky and BB Polinova: the leading role of living matter in the migration of atoms in the natural landscape and the biosphere as a whole, communication elements geochemistry in the natural landscape and the biosphere as a whole, perceptions of landscape-geochemical systems and geochemical barriers and the impact of these relationships on the migration of man-made substances.
In papers Alexeenko VA [ 9 ] examined the challenges facing this science, including those related to the possible negative consequences of human activities. Theoretical propositions environmental geochemistry outlined in close connection with the practical issues of economic activity. It contains a large number of illustrations.
Malyshev LL in his "Theory and methods of landscape-geochemical analysis and assessment of the environmental condition of the territories» [ 10 ] The technique of landscape - geochemical analysis and assessment of the environmental status of the areas (algorithm criteria system indicators), which was tested in the areas of influence of nuclear power plants, industrial zones, agricultural landscapes, urban landscapes, recreational areas. Classification principles defined the basic types of landscape - geochemical structure.
So the basic principles of landscape ecology applied in practice for all industrial enterprises and allow to identify the main patterns of anthropogenic pollution.
Main patterns of spatial distribution of pollutants discussed in the article "Industrial air emissions - the source of contamination of the soil» [ 11 ]. A brief description of the types of soil degradation due to pollution.
Monograph devoted to the problems of soil in urban areas, the authors NG Fedoretc and MV Medvedev [ 12 ] noted that heavy metals received at the soil surface, accumulate in the soil mass, especially in the upper humus horizons and slowly removed their concentration decreases sharply with depth, and clay minerals contribute to the accumulation of organic matter and.
In his work Medvedev MV, Fedoretc NG, AS Yakovlev [ 13 ] analyzed the characteristics of manmade pollution. Conclusion - the amount of heavy metals in the upper horizon exceeds by several times the amount that is spent on the further transformation of the biota and takeaways in the underlying strata in the various chemical compounds.
literature review showed that many questions anthropogenic landscape changes on the areas of coal mines have not been studied. Especially it concerns the influence of local landscape factors on the concentration of pollutants. Exploration of these factors is devoted to this master's work.
Geological characteristics of the object of research
Stratigraphy and lithology
The geological structure of the field of mine attended deposition suites C25, C24 and C23 Middle Carboniferous. Stratigraphically overlying strata (Formation C26, C27) belongs to the fields of mines them. Zasyad'ko, Krasnogvardeyskaya, Ganzovskaya-2.
Carboniferous deposits are poluskalnyh and rock (monoclinally-seated mudstones and siltstones with rare interbedded limestones), overlain by Quaternary formations represented loess loams and clays up to 15 m and the soil-plant-bed capacity of 0.3-0.5 m
These deposits from the surface of a large territory covered by technogenic soils of different capacities.
Stretch rocks south-west, the fall in the north-west at an angle of 10 degrees. Siltstones greenish-gray, brownish-gray (by impregnation with iron hydroxides in areas of intense fracturing), with mica flakes along the bedding planes. Siltstones uneven fracture. Mudstones greenish-gray, weathered, weathering cracks closed, iron hydroxides are present in the form of streaks. Brownish-gray limestones occur as interlayers capacity 0.3-1m, badly fractured.

Tectonics
The mine is located in the southeastern part of the young wing Kalmius Toretskoy-basin, in the central part of the Donets-Makeevsky geologopromyshlennogo district. Tectonic due to location of a mine field in the transition zone of tectonically simple western part of the complex to the east.
The mine is located in the footwall of the regional wing of the French thrust, its boundary structural elements are: in the west - Frantsuzky thrust (supine wing), south-west - Mushketovsky thrust (hanging wall), in the east - Kalinin thrust (hanging wall) . Above thrusts are stepwise structure and characterized by the presence of powerful and crush zones of intense fracturing. In the zone of crushing and near tectonic contact developed small folding and tuck recovery and offshooting melkoamplitudnye violations.
From French genetically related thrusts Cross, Tsentrllny, Coke, Pastukhovsky, Ordzhonikidze. Kalinin thrust from its hanging wall is accompanied by a number of violations (one of them thrust D2), which greatly complicate the tectonic structure of the estimated area in the eastern part of the mine field.
With Mushketovsky thrust associated with the formation Kalmiusskogo reset, reset "A», № 2.
It should be noted that the zones of tectonic disturbances are not stable and are subject to so-called "shifting of" in response to seismic crustal movements of varying intensity. Wherein the blocks divided tectonic faults move in vertical and horizontal directions relative to each other.
Carboniferous rocks in tectonic (geodynamic) zones fragmented fracture system in the same direction (within one zone) and these fragmentation zone extended to a greater depth, dividing the study area into several blocks.
In the north-eastern part of the reserve unit in the hanging wall of the Cross-thrust in the area of its junction with the French and Kalinino thrusts identified by the strata anticline h10, h8. By multiplicative forms tectonics relates sloping syncline in reservoir h5.
Disjunctive form tectonics presented disorders predominantly thrusting type, marked the development melkoamplitudnyh discharges [ 14 ].
Carboniferous
In the Middle Carboniferous sediments, related to the field of 54 mines coal seams and interlayers. 11 of them attain the conditioned power to the entire area or in individual areas.
In retinue C25 estimated layers k51, k5, k42B, k4. Very thin layers. A characteristic feature is the presence of erosion and thinning to broken power, which reduces their commercial value.
Most productive formation is C23. Contains 16 coal seams, of which 5 are the main reservoirs of industrial value (h10, h8, h7, h6, h5). In addition to working coal seams within the field of mine are low-power, highly unstable formations. Their thickness 0,05-0,40 m
During exploration and appraisal of the mine field, it was found that the toxic elements in coal are sulfur and mercury [ 14 ]. Their content in some layers exceed the limits at which the formation of toxic substances exceeding MPC.
Average sulfur content of salable coal (for the period 1983 and 1990) was 2.3%, significantly higher than the allowable limit, and in 2014 was 3.2%. The mercury content far below the limit at which the compounds may be formed.
Arsenic, beryllium and fluorine below the limit at which the possible formation of toxic compounds concentrations exceeding the MAC, which allows them to be classified as potentially toxic.
Average and maximum level of potentially toxic elements (manganese, lead, nickel, vanadium, chrome, cobalt) below the level at which the formation of toxic compounds. Exceeding MPC.
Ecological characteristics
Air pollution
Emissions ventilation air flow when mining coal seams accompanied by the removal of the workings of carbon dioxide, methane, oxides of blasting, dust, condensation, heat and other impurities.
According to the literature [ 15 ] daily coal dust ejected from 0.1 to 0.18% of the total daily production of methane from 200 to 300 m3, dioxide emissions from 35 to 65 thousand m3, thousands of cubic meters of oxides produced during blasting operations from 180 thousand to 360 kJ of heat.
Conclusion outgoing air stream from the mine to them. MI Kalinin carried ventilation shafts with layers smolyaninovskoy Formation mainly trailers barrel. CO2 released into the atmosphere - 4608 m3/day; CO2 - 944 640 m3/day; CH4 - 13824 m3/day. There are a number of stationary pollution sources os

At autopsy, the preparation and in the process of coal mining on the surface is given a significant amount of material that is stored on the surface in the dumps.
Temperature dumps formed under the influence of oxidative processes of sulfur impurities contained in coal dust and rock, as well as the temperature of the atmosphere. When burning heap of rocks formed an additional source of pollution and atmospheric origin. Combustion sources dumps are sources of intense steam and gas emissions. In the greenhouse gases methane, carbon oxides, sulfur, nitrogen, hydrogen sulfide and other compounds, and a variety of radionuclides. In places the gas jets on the surface of the heaps formed technogenic minerals, of which the most prevalent native sulfur and ammonia.
Soil
Upper layer section presents soil-vegetation layer, shown with black soil by plant roots, has a capacity of from 0 to 1.4 m and distributed in fragments.
In most of study area lie anthropogenic (bulk) soils presented a mixture of black earth, loam, slag, gravel, broken bricks, stones. So heaps posted overburden, sludge pit in sediments formed during the first clearing of the city pond. On the site there is a large number of landfills for household and construction waste. All these formations constitute anthropogenic layer of varying thickness, reaching a few tens of meters heaps.
On the industrial site of the mine waste dumps are located, which takes a considerable amount of storage host rocks. Kalinin mine waste dump is burning. Combustion sources dumps are sources of intense steam and gas emissions. In places the gas jets on the surface of the heaps formed technogenic minerals, of which the most prevalent native sulfur and ammonia.
Newly formed mineral forms are unstable and easily destroyed, form highly mobile ions that contribute to pollution of ground and surface waters. Set enrichment of local areas on the surface dumps thallium, antimony, mercury, lead, germanium, chlorine, sulfur, arsenic, bismuth, which, under the influence of acid precipitation may form easily movable compounds contaminating soil, groundwater and surface water.
In order to determine the status of soils was conducted Lithochemical sampling grid 500h500m. Samples were taken 20 points method "envelope". Samples were collected at each of two levels deep: 0,0-0,05 m and m 0,05-0,020
According to the results of testing along with heavy metals in soils and sediments found in the territory of the whole complex of defined organic compounds, ie formaldehyde, acetone, methanol, benzene, phenol, dibutyl disulfide, monoethanolamine, acetophenone, pyridine, toluene, styrene, chlorobenzene, xylene, butanol, dimethyl phthalate, thiocyanates, cyanides and oil.
Hydrosphere pollution
When mining operations and coal aquifers are opened resulting in a need in the organization for the purpose of drainage pumping mine water to the surface and its treatment prior to discharge to surface waters [ 15 ].
Mine dewatering system comprises: pumping mine water to the surface, horizontal three-piece horizontal tanks, disinfection liquid chlorine in the chlorination and then discharge into the pond in the gully Ignatievskaya doosvetlenie then the water from the pond flows into the city pond. In water samples collected in the underground workings of the mine and in places on the surface relief determined following organic compounds characteristic of technogenic load Donetsk-Makeevka promuzla acetone, acetophenone, difenilol propane, pyridine, methanol, toluene, chlorobenzene, styrene, butanol, xylene , ortho-xylene, metaparaksilol, cyanides, thiocyanates, oil.
Of the organic matter content is defined in the relevant phenol - from 0.001 to 0.021 dm 3, monoethanolamine - from 0.06 to 0.23 dm 3, dm 3 0,01-0,062 formaldehyde, benzene 0.01 0.02 dm 3, oil 0.01-0.25 dm 3.
Remaining organics contained in amounts below the threshold sensitivity of the method of determination.
Sources appearance in mine waters phenols can be considered:
- Coal, its oxidation during production due to mechanical failure;
- Vegetation, its expansion, delivery degradation products in groundwater, and with them in mine water;
- Lubricants (oil emulsion), and their losses during use;
- Air contaminated with phenols.
The causes of oil in mine waters are additives and emulsion are used as lubricants, various kinds of mineral oils and fuels, natural oil separation and biogenic carbons, which are products of microorganisms.
Availability in mine waters formaldehyde may be associated with coal mining at the analyzed company. Its presence in the important content can be associated with the work in paint shops and general development pressure on the area of Donetsk-Makeevka industrial center, including mine field, since formaldehyde is widely used in the manufacture of dyes, medicines, as a disinfectant, in the manufacture of plastics based on formaldehyde resins phenolics.
Research Methods
The paper is the following factual information:
-
• Geological maps, charts, plans, sections of the object, environmental reports;
• Laboratory studies of the composition and quality of groundwater (laboratory made "Standard") on the following parameters: suspended solids, COD, BOD, ammonia nitrogen, nitrite, nitrate, chloride, iron (total), salinity, sulfates, petrochemicals, phosphates. Samples are taken regularly from the sump inlet (before treatment) and the output (after cleaning), as well as in a pond in the gully Ignatievskaya, sample volume - 5 liters. Sampling was carried out four times a year.
• Field dual soil sampling points (on two levels: the soil and ground 0-0.05 0.05-0.20) and bind to a coordinate axis.
Primarily been systematized data from previous studies and conducted testing of soils and waters of the study area.
Soil sampling points (on two levels deep) were compared with the location ravine network dumps, industrial buildings, etc. Then, based on data on the MPC (mg / kg) (if absent, the regional background) coefficients were calculated concentrations of heavy metals. At the same time as the regional background I used the average contents of elements in soils Reserve Azov. When using regional background pollution was considered provided above this dual background. Further elements of the complex was calculated total pollution index for each sampling point.
Next the complex elements was calculated total pollution index for each sampling point.
Analysis of water sampling was conducted as follows:
-
• Has established by calculating the coefficient of concentration of substances for the entire study period. When calculating the values used PDS established for enterprises.
• Conducted study of changes in the values of the concentration of substances in space and time.
Were found statistical characteristics, correlation, regression equations are derived for the composition of mine waters and soils and subsoils in the target object. Calculated by the equation will determine the dependence of the content of the main components of mine waters and Soils from other indicators that are in it.
According to the research were built monoelementnye map the distribution of elements in soils territory, as well as the total soil contamination map to classify the territory of the general level of contamination. For the waters were constructed graphs of the content matter of the seasonal data and space throughout the chain mine water - Kalmiusskoe reservoir.
Data processing were used programs such as Microsoft Office Excel, SPSS, Surfer, MapINFO.
Current and expected outputs
A result of the work we have constructed monoelementnye map the spatial distribution of elements on two levels depths of soils: 0 - 0.05, 0.05 - 0.20 m Identified two groups of elements that differ in depth of maximum concentration. The first group contains elements which are characterized by concentration in the soil to a depth of 0.2 m: Ag, Ba, Cu. A second group of elements, which are concentrated at depths of 0.05 to 0.20 m The latter attributed: Pb, Nb, Mn, Sn, Zn.
Distribution of geochemical anomalies in area indicates their confinement to the main sources of pollution: waste dumps in the east and north of the site, the production site to the south. Notes and influence Valley Kalmius where geochemical anomalies are also marked elements. Such a distribution of elements in soils noted in many studies related to the assessment of soil pollution.
Particular interest is the distribution area of concentration Pb (Fig. 1). As can be seen from the figure, Pb anomalies exceedance in 2 and 3 times confined to the industrial site itself mine, in the zone of influence of mine shafts, as well as in the southern part of the map. In the southern part of the study area is the private sector and road transport to the heavy workload.
The north-west with a correlation anomalies dumps and pond. The award is the latest in a pond cascade ponds mine water.
Author were identified in soils and subsoils abnormal concentration of Ge. This element is a characteristic element for the formation h10, mine being developed at the moment. Although this element is toxic, the study of its distribution and comparison with Spreading polluting elements can bind soil and water pollution from coal mining.
Fig. 1. Areal distribution of Pb concentrations in soil field soils mine them. Kalinin (the meanings of multiple MAC)
Author work found that most of the anomalies Ge combined with anomalies of other elements that are dangerous pollutants soils. From this it follows that the main source of pollution here is mine coal mining.
By total pollution index is related to the investigated area is moderately dangerous territory for which Zc value does not exceed 16 balls.
For a comprehensive analysis of environmental pollution has been studied mine water purification system. Studied the composition of water entering the sump, after further purification prior to chlorination and finally, before being discharged into the pond in the gully Ignatievskaya.
Also conducted analysis of water after treatment in different seasons. As an example, Figure 2 shows the behavior of nitrates in the water within a few years. Concentration is normalized by the PDS.
Main results of these studies the following
As seen from the figure, until 2013 was scheduled trend of increasing nitrate content, and then the concentration of stabilized and began to decline somewhat. In general we can say that for 4 years traced a slight increase in the content of this component in purified and ready for discharge into streams mine water.
Nitrate content in mine waters associated with the decay products of plant and animal origin.
PDS Outreach and chloride concentrations, which began to rise with the fall of 2010. The analysis showed that for 4 years sulphate content in mine water decreased slightly, whereas the iron content decreased in 2010 by almost 2 times. The declining trend in iron concentrations in mine water continues.
MINE waters mainly characterized obschekislotnaya sulphate and aggressiveness. For example, the chlorides are present in mine water, and reacted with lime to form insoluble calcium chloride so enhances corrosion by concrete.
Graphics were constructed spatial variation of the content of substances in the chain: mine water - Kalmiusskoe reservoir. Graphs of 2 seasons can deduce the following pattern: mine water, ready for discharge contains most of the components in elevated levels. After the reset, these waters of a retention pond in the beam in the water last Ignatievskaya content of contaminants increases. Ultimately water beams reach Kalmiusskogo reservoir, wherein the content of these components increases. Such a feature is awarded for the nitrates, sulfates, chlorides, solids, but characterized by the reduction of iron content in the water reservoir and the beam after mixing with water silo. This may possibly indicate that iron is precipitated as insoluble compounds and thus self-cleaning occurs in this water component.
Conclusion
During the research were built monoelementnye map the spatial distribution of elements in soils (0 - 0.05) and soils (0.05 - 0.20 m). Identified two groups of elements: the first group includes elements that are characterized by concentration in the soil to a depth of 0.2 m: (Ag, Ba, Cu), the second group of elements, which are concentrated at depths of 0.05 to 0.20 m (Pb, Nb, Mn, Sn, Zn).
Basic areal anomalies are confined to man-made sources of pollution: waste dumps in the east and north of the area, industrial area in the south; noted the influence of the river valley Kalmius. Identified trends are fully confirmed the nature of the distribution of Pb at the test site.
Distribution was studied in soils and subsoils Ge, which will link the contamination of soil and water from coal mining.
By total pollution index is related to the investigated area is moderately dangerous territory.
For a comprehensive analysis of environmental pollution has been studied mine water purification system.
Study of mine water treatment system revealed: 4 years observed a slight increase in the nitrate content in the purified and ready for discharge into streams mine water that may be associated with the decay products of plant and animal origin. Beginning in 2010, the chloride content increases, while sulphate and iron decrease, but at different rates.
Reset treated mine water into the ravine Ignatievskaya increased the contents of contaminants in its waters. The same is observed waters p. Kalmius. In the latter case, this is true for all test components in addition to iron, which when released into the water reservoir and the beam falls in the insoluble residue.
In general, the results of it can be noted that water pollution and of soils typical for this type of enterprise.
