摘要
煤炭开采进入深部以后,凸显许多问题,例如采空侧巷道的较大围岩变形,严重影响巷道的安全使用。针对阳泉煤业集团公司二矿470水平南翼主运皮带巷围岩变形的研究,探析普通水泥注浆加固及化学注浆加固改善巷道维护状况,较大程度地降低了采空侧巷道维护难度,确保了矿井安全生产,并促进了采空侧巷道支护技术的发展。
On the analysis of surrounding rock deformation around the main belt conveyor in No.470 horizontal south wing in No.2 mine, Yangquan Coal Group, regular cement grouting reinforcement and chemical grouting reinforcement were used to improve the roadway maintenance, which reduced the maintenance difficulty, ensured the safety production, and advanced the supporting technology for the roadways alongside the goaf.
