RECLAMATION OF DISTURBED LAND DURING EXTRACTION MINERAL
The article deals with the issues of recultivation of disturbed territories during gold mining in the Amur Region. During the extraction of minerals, the components of the natural environment are disturbed: the fertile soil layer, the hydrological regime of rivers, vegetation and the natural landscape. The projected areas of the disturbed lands under study are 203.2 hectares. Analysis of disturbed lands during gold mining by the dredging method for two objects showed that each type of disturbed lands will affect, to one degree or another, the components of the environment. The resulting quarry excavations lower the level of groundwater in the river valley, which leads to the withdrawal of a significant part of the runoff. The estimated volume of work on reclamation of disturbed lands amounted to 2660.9 thousand m3 for objects, including: layout of overburden dumps 1233.0 thousand m3; lay-out of gale-efel dumps 1097.5 thousand m3; elimination of engineering structures 65.8 thousand m3. On lands that are allotted for temporary use, it is necessary to carry out a technical and biological stage of reclamation. The biological stage of reclamation includes reforestation. Reclamation of technogenic territories minimizes the negative impact of the implemented measures.
