Research and Practice of"110 Construction Method"Technology in 110501 Fully Mechanized Caving Face of Pangpangta Coal Mine
In response to the problems of tight mining succession and low coal resource recovery rate caused by leaving coal pillars for mining in Pangpangta Coal Mine,the 110501 fully mechanized mining face is taken as the research object,and the"110 construction method"of cutting the roof to relieve pressure without coal pillars and self forming roadway is proposed for mining.A constant resistance and large deformation anchor cable reinforcement support and roof pre cracking cutting seam hole layout scheme are designed.The field application results show that the adopted technical scheme effectively controls the deformation of the surrounding rock of the 110501 belt roadway,resulting in the recovery of approximately 58 000 tons of coal pillar resources in the 110501 fully mechanized mining face and the creation of approximately 34.8 million yuan in economic benefits.
