摘要
针对综采放顶煤工作面运输顺槽原支护设计下巷道围岩变形严重的情况,通过采用加密支护、优化支护参数等措施,控制了巷道围岩变形量,两帮移近量稳定在270 mm,顶底板移近量稳定在205 mm,支护效果良好。
Aiming at the serious surrounding rock deformation of the roadway under the original support design of the transportation gateway in the fully mechanized top coal caving working face,the surrounding rock deformation of the roadway is controlled by adopting the measures of densifying support and optimizing support parameters.The approach of the two sides is stable at 270 mm,the approach of the roof and floor is stable at 205 mm,and the support effect is good.
