摘要
针对10710工作面机巷施工灰岩探查孔过程中出现的问题,从底板岩层应力分布状态方面分析,寻找钻孔变形的原因,提出防治措施,避免类似事故发生。
10710 Face machine roadway construction limestone exploration holes have emerged in the process. From the rock bottom state of stress distribution analysis to find the cause of the deformation bored, prevention and control measures, to avoid similar accidents.
