摘要
为解决新疆和什托洛盖矿区侏罗系含水复合超软岩稳定性控制难题,通过现场实测、理论分析和室内测试等综合实验手段对该矿区围岩稳定性进行分析,以沙吉海煤矿+550 m水平井底车场为例,利用恒阻大变形锚杆(索)耦合支护体系为核心,积极探索软岩治理的新途径,新方法,取得了显著成果,可为后续矿井建设和围岩治理提供可靠借鉴。
In order to deal with the stability control problem of aqueous composite super soft rock of Jurassic system of Heshituoluogai mining area in Sinkiang, taking the ＋ 550 m level bottom of Shajihai coal mine as an example, the coupling support system of constant resistence large deformation anchor rod （rop） is adopted and some new methods and approches are put forward to solve above problems in line with the analysis results of stability of surrounding rock in the mining area by using the methods of field observations, theoretical analysis and indoor test. According to the research results, perfect effects are ac- quired and it can provide some reference for the relative engineering practice in the future.
