Abstract

The natural conditions for the formation of coal deposits in different regions of the globe are the same, all of them belong to reservoir sedimentary deposits and differ only in the degree of metamorphism and tectonic disturbances. In this regard, coal deposits of the Kuznetsk basin (Kuzbass, Western Siberia, Russia)) that have no analogues in nature are unique. Here are all sorts of options for the occurrence of coal seams both in terms of their thickness, dip angle, number, and the degree of disturbance by plicative and disjunctive disturbances. The article presents some results of research on ways to reduce coal losses in open pit mining during its extraction by draglines. The study was carried out on the example of deposits in Kemerovo region with coal seams in an inclined and steep formations, which allows analyzing the possibilities of applying the proposed technological solutions in the widest range of specific mining and geological conditions.
