Complex-mechanized development of powerful steep formations with the laying of the deposit

Abstract
The problem of development of thick steep seams with backfilling has become especially acute in Kuzbass, where due to a number of circumstances of technical nature it is required to significantly expand its use, while coal mining with backfilling is developing here very slowly. The unpopularity of backfilling in Kuzbass is explained, first of all, by the low efficiency of the mining systems used there. Thus, excavation of thick steep seams with backfilling is still carried out by the old systems, with division into layers.
