| 摘 要： | 针对阳泉矿区瓦斯赋存特点,通过对比分析各类瓦斯抽放方式指标,从而得出经济、技术可行的最优抽放方式;阳泉矿区单一煤层采用U+L型通风方式的工作面,大口径钻孔抽放方式是最佳选择和发展方向;15#煤层综放工作面采用U型通风方式和走向顶板岩巷抽放方式比较优越。

| Abstract: | Based on gas occurrence characteristics in Yangquan coal mining area,an extraction method with economic and technique feasibility is determined through correlation analysis of every kind of gas extraction indexes.It means that for single mining coal seam the optimum selection and development direction are U+L ventilation and large hole gas extraction;for combined mining working face of 15 # coal seam the U type ventilation and the gas extraction from roof strike direction rock road way are relatively better. |

| Keywords: | coal mine drill hole roadway gas extraction |
