| 摘 要： | 随着综合机械化放顶煤开采发展的不断深入，3．5m～5．5m的较薄厚煤层采用综放开采逐渐取得了普遍的认同。叙述了针对顶煤厚度薄、易破碎，造成放顶煤混矸严重的特点，通过综放采场放煤试验对比，确定的诸如放煤方式、关口原则等放煤工艺参数，旨在为降低混矸率，提高回收率提供依据。

| Abstract: | With the fully mechanized caving mining development,3.5 - 5.5 meters thick coal seam is the fully-mechanized sublevel caving mining gradually got of the general approval.According to the top-coal is thin, easy broken, cause top coal mix gangue serious,this paper through the fully mechanized caving mining contrast test, looking for reasonable put coal process parameters, such as put coal at the way and control principle, to reduce mix bottles rate, improve recovery. |
