摘要
文章分析论述了祁东煤矿7124工作面瓦斯抽放治理的必要性,结合工作面具体情况,研究了高瓦斯工作面顶板高位钻孔瓦斯抽放技术。通过实践,取得了良好的效果,实现了安全生产和高产高效。
The paper analyzed and stated the necessity of the gas drainage and control for No.7124 coal mining face in Qidong Mine. Combined with certain conditions of the coal mining face, the paper studied the gas drainage technology with high level boreholes in roof for the high gassy coal mining face. After the practices in the coal mining face, excellent results were obtained from the coal mining face. The coal mining face reached to a high production and high efficient coal mining face.
