摘要
为掌握亭南煤矿302综放工作面开采对两巷的超前影响范围和强度,对超前支护方式的合理性进行评价,通过超前支护支架立柱的工作压力监测分析以及工作面巷道变形量观测分析,确定了302综放工作面超前影响范围约为25m,工作面开采对两巷距工作面10m内的巷道影响较大。现场观测巷道整体变形量比较小,最终确认302综放工作面超前支护方式合理。
In order to understand the advance influence range and intensity of mining to the two-roadways of Tingnan Coal Mine, we evaluated the reliability of the advance support, according to the work pressure monitoring analysis of the advance support and the observation and analysis of the deformation of the two roadways, influence range of the 302 working face to the two-roadways is 25 meters, and the working face has a larger influence to the two-roadways within 10 meters, and the overall deformation of the roadway is relatively small. Finally, we confirmed that the advance support in 302 fully mechanized top-coal caving face of Tingnan Coal Mine is reasonable and reliable.
