On the issue of backfilling operations in the mined-out space in the Prokopyevsk-Kiselevo district of the Kuznetsk Basin
Abstract
The question of the rationality and necessity of mining thick steeply dipping coal seams prone to spontaneous combustion with backfilling of the mined-out space with waste rock should now be considered definitively resolved. In this regard, the choice of the method for performing backfilling operations is of great importance. The correct choice of the method for performing backfilling operations will ensure a stable backfill mass, which will increase work safety and allow coal to be mined without leaving pillars and the resulting coal losses. The choice of the method for performing backfilling operations is determined by two main factors: a) the mining systems used and b) the nature and properties of the backfilling materials that can be obtained in each individual case. It is clear that in choosing, it is necessary to consider the specific features of each type of backfilling operation.
