南凹寺煤矿综采工作面停采收尾支护技术研究

Study on the Technology of End-stop Support in Fully Mechanized Face in Nan Ao Si Coal Mine

对南凹寺煤矿30405综采工作面停采条件进行分析,提出停采技术总体方案,从回撤通道支护设计及回撤通道锚网索支护技术两方面进行了深入研究,通过数值模拟,其结果表明支护效果很好,为后续有相同条件的煤矿综采工作面停采收尾支护技术研究奠定了科学基础。

By the analysis of the stop mining condition of 30405 fully mechanized working face of NanAoSi Coal Mine, put forward the overall scheme of stopping mining technology, through the numerical simulation,determinate the recovery room support design method and parameter, the results showed that the support effect is well, which laid a scientific foundation for the same conditions of stopping mining supporting technology.
