| 摘 要： | 切顶巷防治技术是指预先在工作面上顺槽与瓦斯高抽巷之间开挖一系列巷道(切顶巷),对顶板进行弱化,当工作面推进到切顶巷区域时,顶板发生破断,避免形成大面积悬顶,从而降低冲击危险性。以桃山矿为工程研究背景,通过设置切顶巷降低了冲击危险性,取得了显著效果,验证了薄煤层群开采切顶巷防冲技术的可行性。

| Abstract: | In this paper,cutting roof roadway prevention technology is previously tunneling a series of roadways between upper crossheading and gas high pumping lane to weaken the roof.When the working face advance to the cutting roof roadway region,the roof would be broken to avoid large roof hanging,the impact of risk is reduced.Taking Taoshan Mine as research object,the rock burst hazard is decreased with the cutting roof roadway,and notable effect has been made,which proves the feasibility of cutting roof roadway rock burst prevention technology in thin coal seam group mining. |
