Abstract:The paper introduced general situation of a coal face in Shanjiaoshu Coal Mine and its mine pressure monitoring purpose, content and problems that need attention, and gave a scheme of mine pressure monitoring, collected and analyzed mine pressure data. Effective treatment measure can be adopted by monitoring and analysis to ensure safe-mining, and results of mine pressure monitoring and analysis has a positive significance for understanding and knowledge of mine pressure behavior, as well as reasonable support selection and improvement of other mining faces in the same mining area.

0引言
贵州盘江精煤股份有限公司山脚树矿采一区18号煤层埋深在800 m左右,为深井开采。在221811运输巷掘进期间,距离风门50 m左右的巷道顶板下沉和片帮现象严重。在掘进到498 m时,由于巷道底鼓和瓦斯压力大且钻孔无法抽出瓦斯而不得不停止掘进。18号煤层为近距离煤层群开采首采层,因此,上覆岩层的压力比较大,导致回采期间巷道维护困难,瓦斯压力与瓦斯含量增大。同时,正在回采的21125工作面的回风巷顶板下沉量超过500 mm,工人无法站立行走。该矿巷修队采取了很多加强支护的措施,但都无法缓解这一状况。山脚树矿之前因为缺乏相关的技术人员与设备,没有进行矿压监测研究。……
