| 摘 要： | 为了分析寨崖底煤矿煤层瓦斯含量影响因素，采用了现场测试、实验室测试和理论推导相结合的方法，对寨崖底煤矿煤层顶底板岩性、岩性边界、煤对瓦斯的吸附常数等因素进行了分析，得出了6号煤层和9号煤层瓦斯含量与顶板泥岩厚度的关系；证实了影响寨崖底煤矿6号煤层瓦斯含量远大于9号煤层瓦斯含量与煤层顶板泥岩厚度、岩性边界、区域地质演化有关；而影响6号煤层瓦斯含量较大的次要因素主要是煤的吸附常数和孔隙率。

| Abstract: | In order to analyze the influence factors of the seam gas content in Zhaiyadi Mine,a method combined with the site measurement,the lab measurement and the theoretical derivation was applied to analyze the roof and floor lithology of the seam,the boundary of lithology,the adsorption constant of the coal to the gas and other factors.The analysis obtained a relationship between the gas content of No.6 seam and No.9 seam and the thickness of mudstone in the roof.The analysis confirmed that the gas content of No.6 seam in Zhaiyadi Mine was higher than the gas content of No.9 seam and was related to the mudstone thickness of the roof above seam,the boundary of the lithology and the regional geology evolution.The secondary factors affected to the gas content of No.6 seam would be the coal adsorption constant and the coal porosity mainly. |
