摘　　要：以瓦斯地质理论为指导,选取煤层埋深、煤厚、底板标高、顶板厚度、底板厚度5个因素,基于DPS数据处理系统,采用灰色关联分析法,应用3种不同的归一化处理对崔家沟煤矿煤层瓦斯含量进行分区研究。通过对各相关因素的关联度计算,并进行排序,对4-2煤层瓦斯含量的影响因素进行了评价。最终确定了埋深、顶板覆盖层厚度、构造是影响崔家沟煤矿煤层瓦斯含量的主控因素,从而为瓦斯含量预测相关因素的选取和矿井瓦斯防治提供了地质依据。By choosing 5 factors of coal seam depth, coal seam thickness, floor elevation,roof thickness and floor thickness, based on gas geology theory, DPS data processing system and grey correlation analysis method, using three different normalization methods, the gas content of coal seam in Cuijiagou coal mine was studied. By calculating grey correlation degree of va- rious factors,and sort,the ilffluence factors of the gas content of No. 4 2 coal seam were evaluated. Finally, the gas content＇ s main controlling factors such as buried depth, thickness of overlying rock and structure were determined,which provide the basis for the gas content prediction and mine gas prevention and control.
