摘要
为解决万峰煤矿深部采区掘进期间瓦斯涌出量大的问题,提出利用巷道施工的先后顺序,采用本煤层顺层钻孔、穿层钻孔交替掩护预抽煤层瓦斯的方式进行掘进施工.同时在煤巷施工期间结合了"四位一体"的综合瓦斯防突措施,利用抽采效果检验、抽采效果验证等方式,有效保证煤巷的安全施工.该技术的成功运用可为类似矿井掘进期间的瓦斯综合治理技术方案提供指导.
Abstract
In order to solve the problem of large gas emission during the excavation of deep mining area in Wanfeng Coal Mine,it is proposed to use the sequence of roadway construction to carry out the excavation construction by alternately covering the pre-drainage of coal seam gas with the bedding drilling and cross-layer drilling of the coal seam.At the same time,during the construction of the coal roadway,the comprehensive gas outburst prevention measures of'four in one'are combined,and the safety construction of the coal roadway is effectively guaranteed by means of the inspection of the extraction effect and the verification of the extraction effect.The successful application of this technology can provide guidance for the technical scheme of comprehensive gas control during the excavation of similar mines.
