摘要
为明确合阳矿瓦斯赋存特征,在收集合阳矿地质勘探、生产阶段瓦斯地质资料的基础上,运用瓦斯赋存构造逐级控制理论以及线性回归的方法,研究了该区瓦斯赋存特征。分析结果表明:矿井地质构造和煤层埋深控制着矿井瓦斯含量的总体水平,煤层厚度与瓦斯含量有明显的正相关关系,顶底板岩性有利于瓦斯的逸散,使合阳矿井瓦斯赋存特征呈现出"总体偏低、纵向升高、翼部降低"的特征。
In order to clarify the characteristics of gas production in Heyang coal mine,on the basis ofthe Heyang mine geological exploration and production stage of gas geological datacollected,the theoryof step - by - step control of gas occurrence and the method of linear regression are used to study thegas characteristics of the area.The results show：mine geological structure and coal seam depth controlthe overall level of mine gas content, there is a significant positive correlation between coal seamthickness and gas content, the top and bottom slate is conducive to the escape of gas. So that thecharacteristics of coal gas in Heyang have a characteristic of ＂lower overall, vertical increase and lowerwing＂.
