摘要
根据义堂煤业现场实际测定的煤层瓦斯含量及煤层埋深,研究了9、10号煤层瓦斯赋存特征,发现该井田在埋深近500m的区域,尚处于瓦斯风化带。文章对该井田的煤田地质史、煤层赋存条件、围岩特性及水文地质条件等影响煤层瓦斯含量的因素进行了分析,得出影响9、10号煤层瓦斯赋存特征的主要原因。
According to the seam gas content and the seam depth measured at the site of Yitang Coal Industry, the paper studied the gas deposition features of No. 9 and No. 10 seam. The study found that the coalfield was at an area with a depth of 500 m and the area was in a gas weathered zone. The paper analyzed the coalfield geological history, seam deposition conditions, surrounding rock features, hydrological conditions and other factors of the minefield affected to the seam ,~as contents. The ~aper obtained the main cause affected to the gas deposition features of No. 9 and No. 10 seams.
