摘要
本文通过对复合顶板冒落机理的分析,确定对复合顶板采用锚网索联合支护,既能够控制顶板下沉还可以稳定离层顶板。通过实践证明:锚网索联合支护能够确保工作面的安全顺利开采,有效降低事故率,使得工作面月产量增加1万t左右;锚网索联合支护技术是解决复合顶板条件下巷道支护的一条有效途径。
Composite roof is constituted by small thickness,fractured and low intensity coal.It is prone to separation, caving and other accidents.For coal mine safety production adversely affects.Based on the mechanism of the composite analysis of caving,it was determined the composite roof steel mesh and anchor combined support.The method can both to control the sinking and stabilize the roof layer.It proved through practice：the method can ensure safe and smooth mined,reduce the accident rate effectively and increase 1 million tons per month.The method can solve the supporting problem of composite roof effectively and provide some guidance for future production practices.
