摘要
以瓦斯钻孔抽采影响半径为研究对象,在施工工艺与抽采时间相同的情况下,分析了穿层钻孔和顺层钻孔工艺对瓦斯抽采的效率,通过采用瓦斯压力指标法测定瓦斯抽采钻孔影响半径,得出穿层钻孔工艺比顺层钻孔工艺效率高15%,为今后矿井瓦斯抽采提供一些借鉴。
The influenced radius of gas drilling drainage was taken as study object, gas drainage rate of crossing drilling and bedding drilling process was analyzed under same construction technology and drainage time, the influenced radius of gas drainage drilling was measured by gas pressure index method, the efficiency rate of crossing drilling exceeds bedding drilling by 15%, with reference for gas drainage down the road.
