摘要
针对王庄煤矿典型煤柱工作面实际情况,通过理论分析计算了煤柱工作面上覆岩层的破断规律,指导了采面的设备选型;并充分利用了已有的巷道和矿井生产系统,缓解了生产接替紧张状况,为类似条件下煤柱工作面的安全高效回采提供了科学有益的依据。
In view of the actual situation of the typical working face with coal pillar in Wangzhuang coal mine, the equipment selection is guided by the theoretical analysis and calculation of overlying rock breaking regular in working face with coal pillar, and the existing tunnel and mine production system are made full use, the production replacement tension is relieved, and a beneficial science basis is provided for the safe and effective mining under the condition of the similar working face with coal pillar.
