厚煤层一次采全高综采工作面矿压规律研究

Underground Pressure Rules Research on Full-mechanized Mining Full Height in Thick Coal Seam

依据许厂煤矿4305厚煤层综采工作面矿山压力观测数据分别对支架初撑力、支架工作阻力、支架阻力增阻情况进行了分析,绘制了实测工作面推进期间支架的平均压力变化曲线,研究了厚煤层一次采全高综采工作面矿压显现规律,为采区煤层开采提供了现实的指导意义。

According to observation data of underground pressure from 4305 full-mechanized mining face with thick coal seam in Xuchang Colliery, this paper analyzed setting load, working resistance and resistance increasing of support mapped average pressure variation curves of supports during mining proceeding. Underground pressure rules of full-mechanized mining full height thick coal seam were obtained and these provide direction for coal mining.
