摘要: 瓦斯突出常常威胁矿工安全及国家、人民财产,是影响煤矿安全开采的最重要因素。影响瓦斯突出的主要地质因素包括地质构造、煤层与围岩、水文地质等。本文全面分析了这三个因素对瓦斯突出的具体影响,结果表明最主要地质因素是地质构造,尤其是断层构造,在煤矿区最为发育,对瓦斯突出也控制最强;其次是煤层与围岩特征,尤其煤层厚度和煤层埋藏深度对瓦斯突出具有较强的控制作用;影响最弱的是水文地质特征,它要造成瓦斯突出还需依靠更多其它因素。希望通过上述分析,为煤矿预防瓦斯突出提供帮助。

Abstract: Gas outburst of coal mine is the most important element in safe exploitation, which threats the security of lots of collieries and the property of country and people. The geological factors which influence the gas outburst most is geological structure, coal seam and wall rock characteristics, hydrological geology and so on. This paper analyzes systemically and profoundly the specific influence of the geological factors which include geological structure. and it turns out that the most important factor is geological structure, especially the fault structure, which exists broadly in collieries, and is the most important factor in gas outburst. Then are the coal seam and wall rock characteristics, and the thickness and buried depth has great influence in it. Hydrological geology is the weakest factor, it can’t make it happen by itself. Based on these analyses, these will provide help for the precaution of gas outburst in future.

Key words: Gas outburst of coal mine, Geological factor, Geological structure, Coal seam characteristic, Hydrological geology
