摘要
煤矿井下的巷道顶板支护对保证井下综采作业安全具有十分重要的作用。针对井下煤层开采过程中工作面经常出现矿压波动,严重影响工作面安全的情况,对煤矿井下矿压的变化机理进行研究,提出了有针对性的巷道顶板支护新方案,有效降低了矿压变化的强度,提升了煤矿井下的综采作业安全。
The support of roadway roof in coal mine plays an important role in ensuring the safety of fully mechanized mining.In view of the situation that the mine pressure fluctuates frequently in the mining process of the coal seam,which seriously affects the safety of the working face,this paper studied the change mechanism of the mine pressure in the coal mine,and put forward a new scheme of the roadway roof support,which effectively reduces the intensity of the change of the mine pressure and improves the safety of the comprehensive mining operation in the coal mine.
