Analysis of coal gas dynamic phenomenon in Xinmi coalfield

  • 摘要: 为研究新密煤田发生低瓦斯含量、低瓦斯压力瓦斯动力现象的原因,解决低指标瓦斯动力现象给生产带来的危害,运用区域构造演化理论分析了新密煤田自印支期至今的构造演化,统计分析了区域内38次瓦斯动力现象和167个采样地点的煤岩坚固性系数f值,结合《防治煤与瓦斯突出细则》及常规实践经验,与新密煤田瓦斯动力现象中煤层瓦斯含量、瓦斯压力做了对比。结果表明,区域内的瓦斯动力现象表现为低瓦斯含量、低瓦斯压力,f值多在0.3以下;基于综合假说机理的研究表明,构造煤普遍发育、煤岩坚固性系数f值小是该现象的深层原因。
    Abstract: In order to study the dynamic phenomenon of low gas content and low gas pressure in Xinmi coalfield,and solve the problem of the damage caused by low index dynamic phenomenon,the paper analyzed the tectonic evolution since Indo-China period based on the theory of regional tectonic evolution,and statistically analyzed 38 coal-gas dynamic events and 167 consistent coefficient f in Xinmi coalfield by combination with “Rules for Preventing Coal-Gas Outburst” and practical experience.The results showed that dynamic phenomenon in Xinmi coalfield was represented by low gas content,low gas pressure and consistent coefficient f below 0.3.The researches based on the theory of comprehensive hypothesis show that widespread development of deformed coal and small consistent coefficient are the deep reasons of this phenomenon.
