摘　　要：针对长春羊草矿由单体柱放顶煤开采转为综放开采存在的技术问题,通过现场实测分析等方法,与炮采工作面矿压显现规律对比,初步掌握了首个综放厚夹矸大倾角复杂煤层较短工作面矿压显现的基本规律和转为综放后存在的问题,摸清了厚夹矸、大倾角等对顶煤冒放性的影响,为今后类似煤层综放开采提供了经验。According to the technical problems in YangCao Coal Company about mining technology transformation form single hydraulic prop caving coal mining to fully mechanized sublevel caving mining, by using analysis on site measurement, and contrasting with strata pressure behavior law of the first shorter longwall face in large inclined angle and complex coal seam, raises the problems occurred after transformation, and finds how thickness dirt band and large inclined angle have influence on top-coal caving characteristics. And this paper will provide some experience with fully mechanized caving mining of similar mine in the future.
