Purpose: to make the model of prognosis of chemical composition and aggressive properties of mining waters on a certain period exploitations and depth of works.
Tasks:
Actuality: the problem of mining waters always is actual for mine enterprise from the moment of action. Mining water with different indexes of chemical composition and aggressive properties negatively influences on the equipment applied at mining. It is therefore necessary to conduct prognostication of these indexes for the increase of efficiency of work of equipment and decline of economic expenses on replacement.
Object: chemical composition and aggressive properties of mining waters and underwaters of mine «Trudovskaya».
Scientific novelty: there was no conducted prognostication exploration of chemical composition and aggressive properties of mining waters and underwaters on the mine «Trudovskaya» to the present day.
Development of deposits of minerals negatively influences on the condition of underwaters, on waters objects. Fallouts surfaces, swamping, submergence of considerable areas and etc can be the consequence of the conducting of mining work.
Mining water render extremely negative influence on a natural environment. Mining waters has a high mineralization as a result of co-operation with the destroyed mine rocks in the mine. Salts of heavy metals, toxic elements, bacteria are accumulated in them, they are aggressive and etc.
Mining water differ by the large variety of chemical composition and properties. They are not drinkable, but high mineralization and inflexibility, aggressiveness, pollution with mineral butters, with the organic matters do not allow to use them without the cleaning in the national economy and for many other aims.
Sour and aggressive mining water, in addition, complicate conditions of development of coal deposits, require applications of more expensive mechanisms, constructions.
Forecast of chemical composition of mining waters is conducted in accordance with the separate periods of deposit exploitation, and is performed with different methods: method of hydrogeology analogies, method of probability and method of expert estimations. Subject of forecast presently is: size of general mineralization, maintenance of cations of potassium and sodium, calcium, magnesium, concentration of heavy metals and toxic elements, maintenance of phenols, sulphuretted hydrogen, self-weighted matters, and also other components and properties of mines waters, are able to render negative influence on the terms of work of miners, safety of environment, equipment and other.
Methods of probability and statistic methods are applied in this work.
