Scientific works, where the character and degree of environmental damage caused by mining enterprises are highlighted, are analyzed. Today's technological solutions often do not meet the requirements of ecologically safe mining works. To eliminate this disadvantage, the methodic approach, directed at saving land resources during horizontal deposit exploitation, is developed. The area of drained lands, volume of transport and other expenses are reduced due to the complete filling of dump space with the overburden rock, which is achieved by means of placing overburden excavations in the center of quarry field. This leads to the increase of the lands, prepared for recultivation, due to filling capital and entry trenches together with moving the work front on the mining and overburden ledges. Understanding the construction of possible variants of system of quarry field opening and extraction is generalized and the algorithm of selecting the rational variant of the deposits extraction system is developed. |
