Abstract

Floor failure and slipping, rib spalling, toppling and slanting of supports and gliding of equipment in the panel generally exist during the top coal caving of steeply inclined thick seam. Technologies of fast moving, zone controlling of surrounding rock and equipment’s stability controlling were put forward through theoretical analysis and field practice. Drawing technologies were also optimized. It shows that key technical problems that limits the production and safe effective mining are solved after applying the key technologies above. Meanwhile, the paper can provide references for the mining of coal seam with similar geological conditions and in the lower level.
