摘要
为了解决祁东煤矿四采区高瓦斯浓度的问题,结合煤层赋存情况与煤矿生产实际,提出采用煤层按自上而下的开采顺序依次保护下伏煤层,实行多重保护,并对煤层瓦斯突出进行预测,对被保护层的卸压瓦斯抽放工艺进行了探讨。
Aimed at the high gas content in No.4 mining area of Qidong coal mine,a top-down mining sequence was proposed to protect underlying coal seams by combination of the occurrence of coal seam and the coal production practice.The gas outburst of coal seam was forecast,and the gas drainage technique on protected coal seam was discussed.
