Conclusions
-
1.
For working thick steep coal seams with a system of level technologies and the back-filling of worked-out space, a standardized set of equipment should be created to advance the face using aggregate support systems with a base that would be able to maintain internal outward pressure, on which the cutter-loader, conveyor, and filling equipment are installed.
-
2.
As a core for building the standard set of machinery to mine thick steep coal seams in the Kuznetsk Basin with the backfilling of worked-out space. The aggregate statically stable and actively controllable mechanized support system of KVZ complex can be used in this context.
