摘要
为了降低高瓦斯采掘工作面瓦斯涌出强度,消除瓦斯超限对生产的影响,采用水力扩孔技术,在煤体中打一定深度的钻孔,利用高压水经钻孔冲刷煤体,使煤体中的吸附瓦斯得以解吸释放。文章以淮南矿业集团潘三矿1792(3)运顺回风联巷为试验点,制定了实施方案,分析了水力扩孔防突措施的卸压增透效果,实现了卸压排放瓦斯的目的。
To decrease gas emission intensity at the working face in the high gas coal seam,diminish the effect on safety production by over limit of gas,the hydraulic flushing technology is used to drill some extend deep holes,and flush the coal in holes and gas adsorbed in coal relieves.Taking return roadway of 1792（3） working face in Pansan Coal Mine as experiment place,the scheme is enacted,the effect of pressure relief and promoting permeability is analyzed,the purpose of gas drainage is realized.
