Introduction

At a time when technology is not standing still, and its rate of growth has recently increased, there is the question of its implementation in the mining industry. Because often it comes to timing and working hours, reduction of power costs for its implementation, namely the automation of the process in many ways simplify and will help solve the problem. In solving geological surveying tasks, nowadays it is important to the introduction of computer technology, which in many ways will accelerate and simplify the process of performing the work.

1. Relevance of the topic

In solving geological - mine surveying tasks relevance is the automation of the process by means of computer technology. In addition to the already existing software packages that help to solve many problems, there are still many unresolved questions, or did not fully resolved - that work on them and we're going to work.

5.1 Counting the amount of finished products warehouses

Stocks of finished products are open rectangular area, equipped with a lifting and transport mechanisms needed to manage the loading and unloading operations. As an up-and-transport mechanisms are used: bridge, gantry, tower mobile cranes, truck cranes and forklifts.

On stationary plants precast concrete storage area has a concrete floor. When storing products from cellular concrete warehouse must be open. Storage area is performed with a slope of 1 ... 2% towards its outer contour for surface water runoff. From the factory floor to the finished goods warehouse serves motorized vehicles or electric trolley, and can also be used overhead cranes, conveyor rollers, electric hoists, conveyors.

The structure of the warehouse equipment depending on its purpose includes collapsible wooden or metal tapes for storage of large-size panels in a vertical or inclined (at 75 ... 80 0 to the horizontal) position, coninductor for individual or group storage products, inventory pads section 6x4 cm, turnarounds, traverses, ropes, roller crowbars and ladders, hand ramps. The roads from warehouses adjacent rows of finished products to major highways and thoroughfares inside. The width of the carriageway roads storage is 8 m, and, if necessary sidetrack without 4m.

Each stack should be a product of the same size or stamps. The position of products in the stack height and must comply with current standards. Area of the warehouse of finished products are calculated according to the formula

,

where ^ A - warehouse area, m2;

Qсут - the volume of goods entering the warehouse at night, m3;

Тхр, Qн, К1, К2 - conventions and covenants of the design standards.

When storing products from cellular concrete warehouse must be open. Storage area is performed with a slope of 1 ... 2% towards its outer contour for surface water runoff.

5.2 Determination of the volume of waste dumps

Extracted minerals to the storage yards, cones or storage site. On the storage areas of stored mineral deposit often takes the correct geometric volume - cone, wedge, or obelisk prizmatoid.

The volume of these figures it is possible to determine the geometric calculations.

The volume of these figures it is possible to determine the geometric calculations.

V = 1/3 H n R2,

where:

H - height of the cone;

R - radius of its base.

n - the number "pi"

If the cone is small, then the height is measured directly by means of leveling rod. With significant amounts of the cone height is determined indirectly. There are two possible cases.

If the cone is located under the ramp or conveyor, the height of which is known, then the height can be determined as the difference between the height of ramps (head or conveyor) and the apex of the cone.

If not possible to determine the height of the cone relative to the surrounding objects or objects, it is possible to calculate the angle of inclination of the cone (cone for regular shape).

Similar methods can calculate the amount of stockpiles of minerals that form other geometric shapes.

The calculations become more complicated if the heap has an irregular elongated shape. In this case, its volume is determined by the method of vertical parallel sections. For this purpose, specific places or at equal distances heap, mentally dissect the parallel vertical planes perpendicular to the axis of the heap (Fig. 16). The volume of each portion between adjacent sections of Si and Si +1 is given by:

V1 = li (Si + Si +1) / 2,

where:

li - the distance between adjacent sections.

The volume V 'and V'' extreme parts of the heap, concluded between its beginning and end and the nearest cross sections determined by the formulas:

V '= l'S1 / 2 and V'' = l'' Sn / 2

where:

l 'and l'' - the distance from the start and end boundaries of the heaps closest to the sections (S1 and Sn).

Full amount of the dump is defined as the sum of the individual parts between sections.

Determination of the vertical sectional area of each blade is made on the basis of the leveling and linear measurements. These findings are applied to a large-scale drawing and determine the cross-sectional area planimeter. The distance between the cross sections are measured directly.

To facilitate such calculations sometimes run shot blade storage areas and establish milestones orientation at the points of alleged cross blade.

Large scraper heaps often form irregular geometric shapes and occupy a considerable area. The value of such stores often calculated by the method of parallel horizontal sections.

To this effect a tacheometry heap, then form it is depicted on the plan in the horizontals. Heap capacity is determined in this case as the sum of the volumes of layers between adjacent horizontal sections. The distance between the sections usually take 0.5-1 m

Volume of the layer, sandwiched between two adjacent horizontal sections is given by:

Vi = h / 2 [(Si = Si = 1) - 1/3S 'i]

where:

h - height of the layer;

Si and Si 1 - area of the loop contour limiting the adjacent layers;

S'-the correction area.

The correction area for each layer is defined in the circuit shown in Fig. 18, where, for example, shows the definition of the correction area for layer III.

Build up of a layer of contour lines and determine its approximate center at O.

From point O is carried out a plurality of radial lines 1, 2, 3 ...

Then we consider the area enclosed between the contours contour layer. At the points of intersection of radial lines with the contour of the upper (smaller in size) horizontal layer build the line segments parallel to the neighboring radial line. For example, at the point corresponding to the line 2 is held segment parallel to line 3, etc. in a circle.

Area formed with elements dSi (shaded in the diagram) are added and the result is the correction area of the third layer S'3.

Calculation of the area produce graphically. To do this on a separate sheet of paper, draw the horizontal radial lines, and the point of intersection lay lengths, respectively, equal segments of lines made between contour lines. The ends of the segments connecting the smooth curve that limits the correction area S'3 for the third layer. This area is defined by a planimeter.

For a rough estimate of the correction area of the blade can be set equal to half the difference between the areas of the lower and upper section of the fiber.

When an uneven surface area warehouse necessarily made her shooting and built a plan with the topography image in the horizontal cross-section of 0.5 or 1 m total blade is determined taking into account the uneven ground warehouse.

Conclusion

In the master's work provides current scientific and practical challenge of developing software tools and automated solutions geological mine surveying tasks on digital models. In the future it is necessary to analyze and study the given tasks to create further algorithm to solve them.
