COMPARATIVE ANALYSIS OF TECHNOLOGIES FOR PREPARING A MINING PILLAR IN THE PROCESS OF DEVELOPING A POWERFUL COAL PLATE

Abstract

When developing development workings across the top layer of coal in a single pass through a thick seam, soil heaving often occurs, leading to changes in the shape and cross-sectional area of ​​the workings. This creates problems with the delivery of materials, equipment, and reassembly of the belt conveyor.
