摘要
为了提高某煤矿坚硬顶板综采面的开采安全性,通过试验研究的方式确定瓦斯抽采高位钻孔最佳位置,以此为基础对高位钻孔瓦斯抽采技术进行优化,并将其应用在某矿工作面当中,优化后瓦斯抽采技术的应用有效的提高了综采面瓦斯抽采效率.
Abstract
In order to improve the mining safety of a hard roof fully mechanized mining face in a certain coal mine,the optimal position of gas extraction high-level boreholes was determined through experimental research.Based on this,the gas extraction technology of high-level boreholes was optimized and applied in a certain mining face.The application of optimized gas extraction technology effectively improved the gas extraction efficiency of the fully mechanized mining face.
