摘要
为解决因采掘接替而引起的工作面瓦斯综合治理中的断缺,大胆采用钻孔法替代巷道法瓦斯治理技术,妥善利用现有资源和技术条件,在底抽巷中施工下向抽采钻孔,解决了因工作面高抽巷掘进不能按期到位而带来的无高抽巷段瓦斯治理难题,并在时间和经济上取得了良好效益,完善了采煤工作面瓦斯综合治理措施,确保了工作面按期、安全、高效回采。
In order to resovle the deficiency in gas comprehensive controlling at mining face, drilling method is used to substitute drivage method daringly. The research shows that through constructing downward drilling to extract in floor suction roadway by properly using various exiting resource and technique the gas controlling problem of no high level suction roadway caused by unpunctual drivage of mining face is settled, indicates that temporal benefit and economic benefit are obtained, gas comprehensive controlling method used in coal mining face is improved while punctual, safe and efficient backmining is ensured.
