孔庄煤矿瓦斯异常原因及其防治措施

Research on reasons and preventive measures of gas unusual gush of stratum in low gas mines

针对近年来,在一些低瓦斯矿井的瓦斯异常涌出区发生了一些重大瓦斯事故,以上海能源股份公司煤层瓦斯含量低,而局部存在高瓦斯区域的孔庄煤矿为例,从影响瓦斯涌出的地质因素和采掘因素出发,详细分析了低瓦斯含量煤层瓦斯异常涌出原因,并提出了瓦斯异常涌出防治措施。也为其它低瓦斯矿井瓦斯异常涌出问题的研究提供思路和方法。

In the past few years, a series of heave gas accidents have occurred in some abnormal gas emission districts in low gaseous mines. Taking the typical low gas Kongzhuang mine for example, the phenomena of gas unusual gush of stratum are probed, the factors of geology and mining are analyzed, and the prevention and management of gas is put forward .Give an example for researching regulations of gas geology in the low gas mines is given.
