摘　　要：为了分析平煤十二矿的己15-1717120工作面以及己煤组其它工作面穿越平煤十矿戊组上山巷道开采时,对戊组上山巷道的影响,利用岩层的强度特性以及煤层开采厚度来确定覆岩破坏高度,得出裂隙带高度最大值远远小于层间距,不会影响戊组上山通风的安全.同时,利用概率积分法,对戊组上山巷道围岩移动变形进行预计,得出上山巷道在煤层倾向方向会产生局部凹凸不平现象,但巷道经过局部维修后不影响巷道的通风功能的结论.最后提出了穿越上山开采的安全技术措施.In order to analyze the effect of mining J15-1717120 working face as well as other working faces of the sixth seam acrossing the fifth seam on the rise-entry,we studied the failure height of overburden based on rock strength,indicating that the maximum height of fracture zone is much smaller than the interlayer spacing,which will not affect the ventilation of the fifth seam rise entry.In the mean time,we predicted movement and deformation of surrounding rock of the fifth seam rise-entry by probability integral method,showing that,although some rugged phenomena can be seen in local place of the rise-entry,the ventilation will not be affected in the rise-entry after it is repaired.Finally,some safety technical measures of mining across over rise-entry are put forward.
