摘要

为改善综放工作面巷道支护效果,以韩家洼煤业有限公司22205综放工作面回风巷道地质条件为基础,对巷道支护方案及参数进行了确定,并在现场进行了实践。根据监测结果,巷道围岩顶底板移近量最大为100 mm,两帮移近量最大为85 mm,围岩变形量较小,巷道稳定性较好。
        In order to improve the roadway support effect of the fully mechanized caving face, based on the geological conditions of the return airway of the 22205 fully mechanized caving face in Hanjiawa Coal Industry Co., Ltd., this paper determined the roadway support scheme and parameters, and carried on the practice in the spot. According to the monitoring results, the maximum displacement of the roof and floor of the roadway surrounding rock is 100 mm, the maximum displacement of the two sides is 85 mm, the deformation of the surrounding rock is small, and the stability of the roadway is good.
