地质构造控制着煤层瓦斯的赋存,造成了矿井瓦斯分布的不均一性.在分析潘集矿区13-1煤层瓦斯地质资料的基础上,利用煤层底板等高线图反映的地质构造信息,在煤层瓦斯含量测试点以1 km2的方形为瓦斯地质单元计算地质构造复杂程度综合系数.研究区根据运储条件共划分6个地质单元,建立地质构造复杂程度综合系数与煤层瓦斯的函数关系.结果表明:矿区各瓦斯地质单元煤层瓦斯含量与地质构造复杂程度综合系数具有明显的负相关关系,两者之间线性关系显著,可见利用地质构造复杂程度综合系数进行未采区煤层瓦斯含量预测是可行的.%Geological structures have controlled coal seam gas hosting, thus caused heterogeneity of mine gas distribution. Based on Panji mine area coal No.13-1 gas geological data analysis, using geologic structural information reflected by coal floor contour map, es-timated coal seam gas content testing point computational element structure complexity coefficient of colligation. According to gas geo-logical unit quantitatively assessed geologic structural controlling on coal seam gas hosting, 6 mathematical regression equations have been established. The study has shown that between mine area gas geological unit coal seam gas content and structure complexity coeffi-cient of colligation has obvious negative correlation, linear relation between them is notable, thus using geological structure complexity coefficient of colligation to carry out coal seam gas content prediction of working areas on standby is feasible.
