瓦斯抽放煤矿矿井中瓦斯涌出量很大，靠通风难以稀释排除时，可用抽放的方法,排除瓦斯,减少通风负担。40年代末,中国在抚顺煤田进行抽放瓦斯试验,50年代应用于生产，抽出数量逐年增加。其后阳泉、天府、中梁山、包头、南桐、北票等矿区也陆续开展抽放瓦斯工作。1981年全国一百多个矿井安设了抽放瓦斯设备，每年抽放瓦斯达3亿米3，供给工业、民用燃料和作化工原料，变害为利。抽放工艺在地面建立瓦斯泵站，经井下抽放瓦斯管道系统与抽放钻孔连接，泵运转时造成负压，将瓦斯抽出，送入瓦斯罐，或直接供给用户。如抽出瓦斯数量较小，或很不稳定，可直接排放到大气中。抽放方法按瓦斯来源不同，可分三类：①抽放开采煤层本身的瓦斯。开采高沼气厚煤层时，瓦斯主要来自开采层本身。抚顺煤矿在煤巷掘进前，从底板岩石巷道打钻穿透煤层,钻孔中插入钢管并将孔口周围密封,瓦斯从插管中抽出。因抽放超前于掘进、回采，使采掘工作减少了瓦斯威胁，此法又称"钻孔预抽瓦斯"。②抽放邻近煤层中的瓦斯。在多煤层矿井，用长壁工作面回采时，顶底板岩层和煤层（包括可采层与不可采层）卸压，瓦斯流动性增加，大量涌入工作面，危害生产。通常在回采前打钻孔到顶板或底板的邻近煤层，回采后瓦斯大量流入钻孔，通过孔口插管，将瓦斯抽出。③抽放采空区的瓦斯。有的矿井采空区大量涌出瓦斯，可在采空区周围密闭墙上插入钢管；也可以从巷道向采空区打钻孔，抽放瓦斯。在条件适宜时还可从地面钻孔抽放瓦斯。优点是不受井下采煤工作的限制和干扰，钻孔抽放工作可超前于采掘工作，抽放时间较充裕。缺点是钻孔较深，需排除孔内积水。发展趋势目前中国瓦斯抽放量只占抽放瓦斯矿井全部涌出量的20％。正在研究瓦斯流动规律，加大煤层的透气性和改进抽放工艺，进一步提高瓦斯抽放量。
