摘要
回采工作面的瓦斯地质因素分析,是煤矿安全生产管理中的重要工作之一,而低瓦斯矿井逐渐发现了瓦斯涌出的异常现象,这对煤矿安全生产具有重要影响。本文以济宁煤田葛亭煤矿为例,运用数理统计方法分析了不同构造块段回采工作面的瓦斯涌出规律,以及影响瓦斯赋存的关键因素,即开采深度与断层特征(封闭或开放),对瓦斯异常现象进行了深入剖析。研究表明,在低瓦斯煤矿可以利用瓦斯涌出量预测断层发育规律,这对低瓦斯矿井瓦斯地质研究具有重要的实际应用价值。
The analysis of gas geological factors in the working face is important to production safety in coal mines. The unusual emission of gas in low gas mines has impact on production safety of coal mine. In this paper, we take the Getting Mine as an example, using mathematical methods to analyze the rule of gas emission in working face, and the key factors affecting the gas occurrence （the depth of mines and the characteristics of faults）. As studied herein, we can forecast the development law of fault by gas emission in low gas mines, which is of great value to the study of the gas geology in low gas mine.
