针对超化煤矿瓦斯地质特征,从地质构造、构造煤以及煤层瓦斯3方面分析了矿井煤与瓦斯突出原因,结果表明:地质构造是控制超化煤矿煤与瓦斯突出的主要地质因素,在地质构造带及附近,应力较集中、煤层厚度变化大、局部瓦斯富集,形成煤与瓦斯突出危险区。依据超化煤矿瓦斯地质规律,提出了加强矿井瓦斯地质研究、建立可靠的煤与瓦斯突出预警系统、强化煤层瓦斯预抽等3条煤与瓦斯突出防治对策,为超化煤矿安全生产提供了技术支持。

According to the gas geological features of Chaohua Mine, from the geological structure, structure coal and seam gas, the paper analyzed the causes of the mine coal and gas outburst occurred.The results showed that the geological structure was the major geological factor to control the coal and gas outburst in Chaohu a Mine.In the geological structure zone and the near area, the stress concentrated, the seam thickness varied highly and rich partial gas formed the coal and gas outbur st danger zone .According to the gas geological law of Chaohua Mine, three coal and gas outburst prevention and control countermeasures, including the enhanced min e gas geological study, established reliable coal and gas outburst early warning system and enhanced seam gas drainage could provide the technical support to the saf ety production of Chaohua Mine.
