摘 要:采用综合指数法分析得到布尔台煤矿22208综采工作面无冲击危险性。对工作面、主运顺槽以及辅运顺槽进行了支护,围岩变形监测结果显示巷道变形量小,整体处于稳定状态,支架提供的工作阻力有效降低了矿压显现对巷道围岩的影响,已有支护方案可继续实施,保障工作面的安全性。The comprehensive index method was used to analyze and obtain that there is no risk of impact in the 22208 fully mechanized mining face of Buertai Coal Mine.The working face,main haulage gateway and auxiliary haulage gateway were supported.The surrounding rock deformation monitoring results show that the roadway deformation is small,and the whole roadway is stable.The working resistance provided by the support effectively reduces the impact of strata behaviors on the surrounding rock of the roadway.The existing support scheme can continue to be implemented to ensure the safety of the working face.
