摘要
为了研究淮南潘三矿11－2煤层的瓦斯赋存规律和主控因素，运用瓦斯地质理论和线性回归的方法，结合潘三矿地质勘探期间瓦斯地质资料和现场实测瓦斯数据，分析了11－2煤层瓦斯赋存特征，探讨了煤层瓦斯赋存与埋藏深度、地质构造、顶底板岩性、煤厚和煤体结构之间的关系。结果表明：煤层埋深、地质构造和顶板岩性是影响11－2煤层瓦斯赋存的主要控制因素，煤厚增加使得瓦斯含量也相应增大，构造软煤的不均匀分布在一定程度上增大了瓦斯突出危险性，从而为潘三矿煤与瓦斯突出危险性预测提供了依据。
Abstract
In order to study gas occurrence regularity in 11-2 coal seam in Pansan Coal Mine and the main in-fluencing factors , the features of gas occurrence in 11-2 coal seam was analyzed and the gas occurrence in de-pendence on coal seam depth , geological structure , roof and floor lithology , coal body structure was discussed . The results showed that coal seam depth , geological structure and roof lithology are the main influencing factors of gas occurrence in 11-2 coal seam .With the coal seam thickness increasing , gas content rises , and the inho-mogeneous distribution of tectonic soft coal induces gas outburst hazard rising to some extent .The study results provide a basic reference to prediction of coal and gas outburst in Pansan Coal Mine .
