羊场口煤矿瓦斯涌出特征及影响因素分析

Analysis of Gas Emission Characteristics and Influencing Factors to Yangchangkou Coal Mine

羊场口煤矿地质构造复杂、断层极为发育,目前主要开采K。。煤层,历年瓦斯鉴定属高瓦斯矿井。采用回归分析的方法分析羊场口煤矿瓦斯涌出特征,并对瓦斯涌出量进行预测。结果表明:地质构造、顶底板岩性、煤层厚度、煤层上覆岩厚度等成为煤层瓦斯赋存的主要影响因素。由于该煤矿的北东部瓦斯涌出量大,东部埋深大,瓦斯含量大,所以分析结果对该煤矿的安全生产具有一定的指导意义。

The geological structure of Yangchangkou Coal Mind is very complex and the fault is extremely developed, which is a high gassy mine, and at present, we are mining the K10 coal seam. In this article, we use the method of regression analysis to analyze the emission characteristics of Ynagchangkou Coal Mine, and predict its gas emission. The results show that the geological structure, the roof and floor lithology, the thickness of coal seam and the thickness of overlying strata are the main influencing factors. In the northeastern part of the coal mine, there is a large amount of gas emission, and the eastern part is buried deep and the gas content is large. This result has certain guiding significance to the safety production of coal mine.
