Abstract
According to the problems of leakage and ram accident during the mining of thin bedrock coal seam working face, taking the 1512 (3) working face as the research background, through the numerical calculation and theoretical analysis to select the size of support, an on-site industrial test is carried out to evaluate the adaptability of the support. The result shows that: the average utilization rate of end resistance of ZZ130000 / 24/50 four-post shield type hydraulic support is 80. 6％, which can ensure the safe recovery of working face and provide some references for the selection of face support under similar conditions.关键词
