摘要： 煤矿沿空留巷开采技术解决了井下留煤柱开采资源浪费、采掘接续紧张等问题，但沿空留巷需要经历两次采
动影响，巷道围岩破坏严重。当工作面顶板为厚层坚硬岩层时，顶板不易垮落，巷道周围岩体应力集中明显，巷道维护
更加困难。为解决此问题，探索厚层坚硬岩层沿空留巷工作面切顶卸压围岩控制技术，以期为相似条件工作面巷道维护
提供一定的参考。

Abstract: The gob -side entry retaining technology solves the problems of resource waste and tight mining and tunneling
connection in underground coal pillar retaining. However, the gob-side entry retaining needs to experience two mining impacts,
and the surrounding rock of the roadway is seriously damaged. When the roof of the working face is thick and hard rock, the roof
is not easy to collapse, the stress concentration of surrounding rock around the roadway is obvious, and the support of the roadway
is more difficult. In order to solve this problem, this paper explored the control technology of roof cutting and pressure relief
surrounding rock in the thick and hard strata gob-side entry retaining face, in order to provide some reference for the support of
working faces with similar conditions.

Key words: coal mine; gob-side entry retaining; roof cutting and pressure relief; surrounding rock control
