摘　　要：针对平朔矿区4号煤层条件,采用理论分析方法研究了浅埋深两硬条件下4号煤层顶煤的冒放性及合理采煤方法。以提高顶煤冒放性为目标,采用数值模拟的方法进行了综放工作面参数及设备选型配套研究。实践表明,浅埋深两硬煤层条件下通过加大综放工作面长度与割煤高度,可以实现安全、高效、高回收率开采。Top-coal caving difficulty degree and rational mining method were analyzed by theoretical method on the basis of the 4th coal-seam condition of Pingshuo Mining area.For improving top-coal caving degree,the parameters of full-mechanized caving mining face were obtained by numerical simulation and the equipments were selected and assorted.Practice showed that safe and high-efficient mining with high recovery ratio would be realized by lengthening mining face and adding mining height in shallow buried hard coal-seam with hard roof.
