摘要
为探索煤矿深井岩巷破碎软弱围岩的支护方法,结合煤矿大巷的支护工程实践,提出煤矿轨道大巷联合支护的设计理念和优化支护方案。结合现场监测数据,对新旧支护方案的效果进行了对比,研究结果表明,采用双网分步联合支护方法,充分发挥并提高围岩的自身承载能力,取得了较经济理想的支护效果。
In order to explore the supporting method of breaking weak surrounding rock in stone drift of deep well of coal mine,combining with supporting engineering practice of main roadway in coal mine,this paper puts forward supporting design concept and optimization supporting schemes of combined supporting between coal mine＇ pathways and main roadways.Combining with field monitoring data,it compared the effect of the new and old supporting schemes,and the results show that the dual-network step-by-step combination supporting method gives full play to and improves the self bearing capacity of surrounding rock,and has achieved quite economic ideal supporting effect.
