摘要
成庄矿二盘区二部胶带机机头硐室随着二盘区胶带机机头硐室附近南北两翼工作面的回采结束,受回采动压影响,硐室底板底鼓影响了胶带机的正常运转。通过对其地质条件、破碎机理及加固原理的分析,提出了对底板和围岩合理的注浆锚索处理技术。
The drive unit chamber of the second belt conveyor in second layer of Chengzhuang mine was suffered from the dynamic mining pressure after the mining of north-south faces and the chamber floor heave affected the normal operation of the conveyor. By the analysis on its geological condition, damage mechanism and reinforcement theory, the study presents the grouting anchoring cable processing technology for floors and surrounding rocks.
