摘　　要：研究表明,钱家营矿5煤瓦斯异常,受煤厚、煤层结构、地应力及顶底板岩性的控制。煤层变异系数大、煤体结构破碎形成了煤层突出的基础;顶底板含泥率高,保存条件良好,导致瓦斯含量高;地应力诱导了瓦斯动力现象的发生。The result shows that gas anomaly：of No.5 Seam in Qianjiaying mine is dominated by seam thickness, seam structure, tectonic stress as well as roof and floor lithologic. The coal seam outburst is based on variation coefficient and structure of coal seam. The gas is preserved better because of the higher mud containing rate in roof and floor, which leads to the high gas content. The occurrence of gas dynamic phenomenon is induced by the ground stress.
