摘要
为解决断层+背向斜构造条件下巷道变形难题,以31006工作面为研究对象,采用"W钢带、金属网、锚索、锚杆"的联合支护方式。试验表明,31006辅助进风巷的变形趋势为"先变快、后变慢、最后趋于稳定",巷道顶板和两帮巷道变形均得到了有效控制。
In order to solve the problem of roadway deformation under the condition of fault+anticline structure,taking the 31006 working face as the research object,the combined support mode of"W steel belt,metal mesh,anchor cable and anchor"is adopted.The test results show that the deformation trend of the 31006 auxiliary air entry is"first faster,then slower,and finally stable",and the deformation of roadway roof and two sides has been effectively controlled.
