| 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。

| Abstract: | 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. |

| Keywords: | shallow buried depth hard coal seam with hard roof top coal caving difficulty degree full mechanized caving mining with large mining height |
