摘    要:为解决综采工作面运输巷端头及超前支护自移式液压支架破坏沿空留巷顶板锚杆、锚索问题,结合运输巷沿空留巷设计实施方案以及端头、超前液压支架相关技术参数进行论证、计算,从而得出沿空留巷顶板补强预紧力锚索支护强度远大于端头及超前液压支架支护强度,综采工作面切顶卸压沿空留巷端头及超前范围内取消液压支架支护是科学合理的。

关 键 词:切顶卸压  沿空留巷  超前支护  预紧力锚索  主动支护

Abstract:In order to solve the problem of destruction of roof bolts and anchors along goaf retaining roadway by transportation heading and advance supporting self-moving hydraulic support in fully-mechanized mining face,the design and implementation scheme of goaf retaining roadway along transport heading and related technical parameters of end and advance hydraulic support are demonstrated and calculated,it is concluded that the support strength of pre-tightening anchor cable for roof reinforcement along goaf retaining roadway is much stronger than that of end and advance hydraulic support,the conclusion of support strength is that it is scientific and reasonable to cancel the support of hydraulic support at the end of gob-side entry retaining and in advance in fully-mechanized mining face.
Keywords:,roof cutting and pressure relief, gob-side entry retaining, advance supporting, pre-tightening anchor cable, active support
