首阳煤矿15206工作面进风顺槽过空区支护设计

Design of Support for the Overhung Area in the Inlet Windway of 15206 Working Face in Shouyang Coal Mine

针对晋能控股煤业集团首阳煤矿15206工作面地质情况复杂、存在采空区,进风顺槽较难通过采空区的问题,重点对15206工作面进风顺槽过空区进行了支护设计。通过对15206工作面进风顺槽过空区进行一次支护、二次支护以及空巷锚网索与木垛联合支护,并进行支护巷道矿压监测,最终保障了15206工作面进风顺槽顺利通过采空区,取得了较好的应用效果。研究成果可为类似工况下的工作面进风顺槽过空区支护设计提供参考。

In view of the complex geology of 15206 working face of Shouyang Coal Mine of Jinneng Holding Coal Industry Group,it is dificult to pass through the hollow area in the inlet windway.Through the primary support,secondary support and joint support of anchor network cable and wooden pallet,and the monitoring of mine pressure in the support lane,the 15206 working face into the wind tunnel through the empty area was finally guaranteed,and achieved a good application effect,which can provide reference for the design of the support of the wind tunnel into the working face under similar working conditions.
