复合支护在松软地层中的开发及应用

Development and Application of Compound Support in the Loose Ground

针对张端井田地质构造复杂,构造应力及矿压显现,从现在巷道的支护理论出发,结合山西焦煤霍州煤电集团张端煤业有限公司在掘进主斜井穿越表土段与强风化基岩层不同岩性松动范围方面,分析了锚网喷及钢筋混土联合支护巷道、加固围岩的作用原理及施工技术,在现场取得了很好的技术经济效益。

In view of the complicated geological structures, tectonic stress and strata behaviors of Jingtian in Zhangduan, starting from support theory of roadway theory now, combining with the aspects of boring main inclined shaft through the topsoil segment and the different lithological loose range of strongly weathered bedrock of ZHANG Duan Coal Co., Ltd.of Huozhou Coal Electricity Group of Shanxi Coking Coal, analyzed the action principle and construction technology of support roadway and reinforcement surrounding rock by anchor net shotcrete and concrete jointly, which achieved good technical and economic benefits on the spot.
