摘要
新疆焦煤集团主焦煤公司24122综采工作面属于坚硬顶板软煤软底倾斜中厚煤层开采的工作面。工作面平均倾角为33°,煤层厚度为2.0 m,煤硬度系数为f=3,且煤层赋存夹矸及煤包石。因顶板为坚硬顶板,虽经过深孔爆破处理,但矿山压力显现,存在严重的安全隐患。结合工作面实际情况,分析了综采工作面的矿山压力并提出防治措施。
Xinjian of soft coal in sloping g coking coal company 24122 fully mechanized mining face is hard roof and soft bottom medium--thichness seam. The average inclination is 33°, seam thickness is 2.0 meters, coal hardness coefficient f = 3, and coal seam has partings and the coal lithocarpus. Due to roof is hard, while blasting through the hole, but the strata pressure behavior, there is a serious security risk. In combination with the actual situation of the comprehensive face rock pressure and puts forward control measures
