摘要
针对原矿压观测存在的问题,通过在急倾斜中厚煤层综采工作面实施矿压在线观测和分析,提高工作效率,增强矿压监测真实性和连续性,通过对矿压在线观测各项数据与工作面瓦斯涌出量进行综合对比分析,初步掌握了工作面顶板动态压力变化与瓦斯涌出量变化关系,为提升矿井顶板灾害防治能力和实现顶板灾害超前预警具有重要意义。
In view of the problems existing in the original ore pressure observation, we implemented online observation and analysis of rock pressure in fully mechanized mining face of steeply inclined medium-thick coal seam, therefore the work efficiency was improved, and the authenticity and continuity of rock pressure monitoring were enhanced. The comprehensive comparison and analysis of the data and the gas emission of the working face has initially grasped the relationship between the dynamic pressure change of the roof of the working face and the change of gas emission, which is of great significance for improving the ability of mine roof disaster prevention and achieving the disaster early warning of mine roof.
