摘要
针对西山镇城底矿2、3号煤层围岩变形量大的松软复合顶板回采巷道,应用锚、梁、网、锚索补强的组合支护技术,控制了复合顶板回采巷道围岩的强烈变形,解决了松软复合顶板回采巷道支护的技术难题,实现了煤巷安全高效掘进。
For the loose and soft roof with big surrounding rock deformation in the caving roadways of No.2 and No.3 seams of Zhenchengdi Mine,the integrated support technique of anchor-beam-mesh-cable is applied.The deformation of supporting rock is under control,and the safe-and-efficient roadway driving is realized.
