摘要
近年来,我国发生了4起低瓦斯矿井瓦斯突出的事故。通过分析,认为低瓦斯矿井发生瓦斯突出事故有以下原因:管理上对于低瓦斯矿井发生的瓦斯异常现象不重视;技术上对低瓦斯矿井瓦斯低的原因不清楚,另外低瓦斯矿井升级不及时。并提出了预防低瓦斯矿井的瓦斯突出的对策:密切关注瓦斯异常区域,运用瓦斯地质理论分析低瓦斯矿井瓦斯低的原因,划出瓦斯风化带的下限,发生瓦斯动力现象后,及时升级。
In recent years,4 low gas outbursts happened in China.Through analysis,reasons are as follows: little attention to the abnormal gas in the management;unclear reasons for low gas in technology,and delayed upgrading of low gas mines.The paper also proposes measures for prevention: pay close attention to abnormal gas areas,analyze reasons according to gas geological theory,mark out the lower boundary of gas weathering zone,and upgrade immediately after gas dynamic phenomenon.
