Mining of coal seams in the conditions of the mine "Raspadskaya" is characterized by a number of significant features that must be taken into account when planning and conducting cleaning works: simultaneous mining of a suite of six converging seams of excavated thickness from 1.8 to 4.5 m, a relatively shallow depth of cleaning works, regular order of cutting excavation pillars.
