摘要
通过对不同钻孔瓦斯抽放量的观测统计,采用数值分析手段,分析比较了钻孔的抽放能力,为矿井提高瓦斯抽放率提供了参考依据。
On the basis of observation and statistics of various drilling gas suction quantities, the suction capacity of drilling was analyzed and compared by using the numerical analysis means. It gave a reference to increasing gas suction rate of mines.
