深部高应力软岩巷道联合支护研究

本文针对深部高应力软岩巷道掘进和使用期间出现的巷道变形破坏严重的难题,结合现场施工经验,应用现场试验与数值模拟相结合的研究方法,分析深部高应力软岩巷道变形破坏原因、规律以及提出巷道矿压控制措施,在煤矿试验区选择锚网梁索喷支护方式进行研究,证实此种支护方式为深部高应力软岩巷道合理可行的支护手段,对深部高应力软岩巷道的矿压控制有一定的指导作用。

Study on the Combined Supporting of Soft Rock at Great Depth under Complex High Stress Condition

Based on the distortion and damage of lanes in deep soft rocks while digging and using,the methods of rests on spot and numerical simulation combined with experience of construction were used to analyze the reasons and regulations of distortion and damage,also the pressure control methods were brought up in this paper.In test zones of coal mine, reasonable and feasible maintenance methods have been proved effective for controlling lane pressure based on different conditions of rock and stress as well as experimental research.
