摘　　要：为提高煤炭资源回收率、减少煤炭资源的损失浪费、延长煤矿的生产服务年限,南庄公司采取了大巷煤柱回收技术实践,通过高强度高预紧力锚杆支护技术实现了对破碎巷道的有效支护,围岩层次注浆技术实现了对巷道围岩的整体性加固,以上两项技术的应用使得煤柱工作面巷道得到有效控制,保障了煤柱的安全回采。In order to improve the recovery rate of coal resources,reduce the loss and waste of coal resources and extend the service life of coal mines,Nanzhuang Company adopted the technical practice of pillar recovery in alleys.The high-strength and high-pretension bolt support technology can effectively support the broken roadway,and the surrounding rock layered grouting technology can integrally reinforce the surrounding rock of the roadway.The application of these two technologies can realize the effective control of roadway in coal pillar working face and ensure the safe mining of coal pillar.
