摘要
以文家坝煤矿+1310m水平大巷为工程背景,经过现场调研后选取合适的抽采设备,制定了合理的钻孔方案,使用长钻孔瓦斯抽采方式进行了瓦斯治理,实现了长距离精准瓦斯抽采的同时,保障了巷道安全、顺利掘进。
Taking the+1310 m horizontal main roadway of Wenjiaba Coal Mine as the engineering background,after field investigation,the appropriate extraction equipment was selected,a reasonable drilling design scheme was developed,and the gas control was carried out by using the long hole gas extraction method,which realized the long-distance accurate gas extraction,while ensuring the safety and smooth tunneling of the roadway.
