摘要
针对矿井高瓦斯、产量大的特点,结合回采工作面的瓦斯来源分布情况,提出了回采及掘进工作面瓦斯抽采的方法,根据其不同工作面的特点设置出各自不同的抽采钻孔布置方式,通过计算设计出相应的瓦斯抽采参数,最终经现场实测得出该开采层的瓦斯抽采方案科学合理,为其他类似矿井提供了一定的借鉴经验。
Aiming at the characteristics of high gas content and high output in mine, combed with the distribution of gas sources in mining face,the method of gas drainage in mining and heading face is put forward. According to the characteristics of different working faces, different layout methods of extraction boreholes are set up, the corresponding gas extraction parameters are designed by calculation.Finally, the gas drainage scheme of the mining seam is scientifically and reasonably determined by field measurement,which provides some reference experience for other similar mines.
