摘要 鲁班山北矿属于高瓦斯矿井。为提高瓦斯抽采率,在1847工作面机巷先后进行两次深孔预裂爆破,累计40天观测和统计爆破孔、控制孔的瓦斯抽放流量,并比照相邻的对比孔情况,得出爆破硐室的所有孔平均单孔抽采量较对比孔高31%,爆破孔的平均单孔抽采量较对比孔高51%,达到预期效果。 Lubanshanbei coal mine is high gas mine.For the purpose of improving gas extraction rate,the deep hole presplitting blast is used in practice.The paper introduced the result of deep hole presplitting blast.
