The assessment of rational use of natural resources in open-pit mining

The purpose of the research was to study the methods of rational use and protection of natural resources when conducting open-pit mining operations. The analysis and the assessment of rational use and protection of natural resources on the example of gold mine "Zolotaya Tyrada" located in the Yenisei district of Krasnoyarsk Region were carried out. The technologies applied to rational use and protection of natural resources when conducting open mining operations were studied. The results of the assessment of the influence of the career " Zolotaya Tyrada" on natural resources were the following: the requirements of rational land use were observed, there was a reduction of losses of land resources under external dumps in connection with refusal of part of desired lands, for minimization of turnover and preservation of the woods of the 1-st group; in connection with the short term of working off the field there was the minimum gap on time between the violation and restoration of lands; actual height and the area of dumps of overburden rocks did not exceed the design, correction of dumps configuration allowed to reduce the influence of works on the environment, to avoid the placement of part of dumps in water protection to a zone of the river of Tyrada; in connection with mountain and deep type of the career which most part was located much above the dominating level of the surface, pollution of underground water-bearing horizons career waters "Zolotaya Tyrada" did not happen and would not occur, artificial reservoir of the career was the accumulator for storm and thawed snow; the actions for rational use of water for collecting, sewage treatment, the lack of dumping of sewage in a stream Valunny allowed to provide the impact on water resources at admissible level; deforestation reduced superficial drain in admissible limits and did not lead to visible changes of hydrological characteristics of superficial water currents of the area; the termination of mining operations will allow to restore hydrological the mode of the region of the field...
