煤矿切顶卸压沿空留巷设计

无煤柱开采是煤矿高效开采的发展趋势。切顶卸压沿空留巷是目前应用最为广泛的无煤柱开采方式。根据阳泉煤业集团安泽登茂通煤业有限公司的实际地质情况,对切顶卸压沿空留巷中的切缝深度、支护锚索及临时支护参数的设计进行了分析,并对其施工过程进行了设计,可为沿空留巷设计提供一定的指导。

Design of Gob Side Entry Retaining by Roof Cutting and Pressure Relief in Coal Mine

Pillar-free mining is the development trend of efficient mining in coal mines.Gob side entry retaining by roof cutting and pressure relief is the most widely used pillar-free mining method at present.According to the actual geological conditions of Anze Dengmaotong Coal Industry Co.,Ltd.of Yangquan Coal Industry Group,this paper analyzed the design of cutting seam depth,supporting anchor cables and temporary supporting parameters in the gob side entry retaining by roof cutting and pressure relief,and designed the construction process,which can provide certain guidance for the design of gob side entry retaining.
