摘要
为了解决平煤股份香山煤矿采掘工作面接替日益紧张的难题,需提高戊9-10-22160运输巷的掘进速度。通过对现场调研观测得到的数据进行整理分析,提出了4种不同支护参数的方案,经过数值模拟确定最优支护参数。该方案经过现场验证优化后,安全、有效,达到了支护的预期目的。
To solve the problems of mining and driving alternation in Xiangshan Coal Mine of Pingdingshan Tian＇an Coal Industry Co. , Ltd. ,it is necessary to improve drivage speed of the Ⅵ9.10-22160 haulage gateway. Four different supporting schemes were proposed though analysing observed data and field investigation. By the numerical simulation, the optimal supporting parameters was determined. Through on-site industrial test and optimizations,it was shown that the scheme is safe and effective,and can achieve the desired aims of supporting.
