摘    要: 急倾斜厚煤层短壁综采工作面与普通长壁综采面矿压显现规律有差别。本文针对木城涧煤矿急倾斜厚煤层短壁开采特殊地质和技术条件,在广泛调研和现场实测的基础上,应用理论分析、数值计算等研究方法,系统地探讨了复杂难采厚煤层工作面的矿压显现规律,确定了急倾厚斜煤层短壁工作面合理的支架工作阻力及超前支护距离。并对现场应用效果进行分析,为类似矿山急倾斜厚煤层的开采提供了工程实践技术依据。

关 键 词:急倾斜厚煤层  短壁综采  矿压显现  支架工作阻力

Abstract:There are differences between steeply inclined thick coal seam short wall combined-mining face and general long-wall combined-mining face in strata-pressure behavior. Aiming at the special geological and technical conditions of inclined thick coal seam short wall mining in Mu Chengjian colliery, on the basis of extensively investigation and field easurement, applying of theoretical analysis and numerical calculation methods, this paper systematically explores the strata-pressure behavior of difficult-to-mine complex thick coal seam mining face, determines the rational working resistance of support and the distance of advanced support in steeply inclined thick coal seam short wall mining face. And analyses the effect of site application, provides engineering practice technical basis for the similar mining of steeply inclined thick coal seam.
Keywords:inclined thick seam  shortwall all mechanize  strata-pressure behavior  working resistance of support
