| 摘 要： | 为研究卸压槽技术在防冲和减少巷道变形中的作用,以忻州窑矿309盘区11#层8931面5931巷为研究对象,根据地质条件,对巷道底板布置卸压槽,同时布设了卸压槽卸压效果观测设备,观测巷道压力及位移变化.结果表明:布置卸压槽可减小应力集中,缓解巷道围岩变形,减弱和消除工作面的冲击地压危险性,有利于巷道保持长期稳定,增加企业的经济效益和社会效益.

| Abstract: | Aiming at rock burst of roadway 5931face 8931coalseam No.11Panel 309in Xinzhouyao coal mine, according to relevant geological conditions, the pressure-relieving groove was excavated on roadway floor, and devices were set so as to observe the press and displacement of roadway. Observation results show that the pressure-relieving groove is beneficial to risk reduction of rock burst and can increase economic and social benefits of enterprise. |
