摘要
针对保护层也为突出煤层并采取高抽巷穿层钻孔预抽煤巷条带煤层瓦斯的情况,在保护层工作面创新应用地面钻井群联合高抽巷瓦斯治理模式。论述了钻井群抽采呈现出的基本规律及地面钻井群抽采与保护层工作面高抽巷抽采间的相互配合关系,并指出了应用联合瓦斯治理模式应注意的问题。
In view of the situation that the protective layer and the outburst coal seam that is adopted in the high drainage roadway to control gas, during mining the protective layer, innovatively applied the gas control mode of the combined high pumping roadway in the surface drilling group. This paper discusses the basic law of the drilling group extraction and the relationship between the extraction of the ground drilling group and the extraction of high drainage roadway in the protective layer.
