瓦斯瓦斯minegas植物在成煤过程中生成的大量气体。又称煤层气。大致可分为可燃烧和爆炸的气体、具有窒息性的气体和具有毒性的气体3种。煤矿中的瓦斯往往单指甲烷(CH4)，是无色、无味，能燃烧和爆炸的气体。地下采矿时，瓦斯往往由煤层或岩层内涌出，污染矿内空气，当其在空气中的浓度超过55％时，能使人很快窒息死亡，是煤矿生产中的主要危害因素。瓦斯与空气混合，在高温下急剧氧化，并产生强烈的冲击波，即瓦斯爆炸。甲烷的燃点为650～750℃，矿井下的明火、吸燃的香烟，煤炭自燃、爆破、电火花、电弧、赤热的金属表面接触，甚至撞击或摩擦产生的火花，都会点燃瓦斯，发生爆炸。瓦斯爆炸产生的瞬间温度可达1850～2650℃，压力可达初压的9倍，爆源附近气体以每秒几百米以上的速度向外冲击，使人员伤亡，巷道和器材设施毁坏。防止瓦斯集聚的基本方法是以足够的风量将瓦斯冲淡，排出地面，但矿井瓦斯涌出量很大时，单靠通风难以降低浓度排除，可用抽放的方法，排除瓦斯，减少通风负担。抽出的甲烷可做工业、民用燃料和化工原料，如抽出的瓦斯数量较小或很不稳定，也可直接排放到大气中。预防瓦斯爆炸的主要措施有：用矿井通风和控制瓦斯涌出等方法，防止瓦斯浓度超过规定范围；控制火源，杜绝非生产需要的火源，如吸烟、火柴、明火照明等。对生产中不可避免的高温热源，采用专门措施严加控制，如只准使用特制的矿用安全炸药和电气设备，加强井下火区管理，禁止在井下拆开矿灯等；定期或自动连续检测工作地点的甲烷浓度和通风状况。
