Abstract

Abstract: According to the serious influence of the dynamic mine strat pressure under concentrated coal pollar of gob in shallow seam longwall mining of shengdong mining area, Combined the example of No.31201 coal mining of Shigetai Mine,the paper analyzed mechanism of the accident,the rotary of gob bedrock by the instability of concentrated coal pollar,then the lower coal seam bedrock was destroyed, the dynamic mine strate pressure was casde by the impact load of the upper and lower bedrock. Adopting measures of blasting of coal pollar、shortening the length of face、yield mining and so on, and guided and validated by the microseismic monitoring、internal displacement monitoring and surface ground observation,through the measures to solve the problem of prevention of the dynamic mine strate pressure,to realize safe production.
