| 摘 要： | 通过对山西沁水盆地中、南部井下煤层宏观裂隙的观测和统计，将其按大小和形态特征分为4级，并在扫描电镜下对显微裂隙进行了系统描述和测量。在分析渗透率与地应力、埋深、裂隙、储层压力和水文地质条件等相互关系的基础上，指出影响本区煤储层渗透率的主控因素是地应力和埋深，在埋深相似的条件下，其他因素对渗透率起着更重要的作用。

| Abstract: | According to measurement and statistics of down coal mine macrofractures were classified into four ranks,and systemically described and measured under scan electron microscope. Based on the analysis of relationship between permeability and ground stress/buried depth, fractures, reservoir pressure, hydrogeological condition, authors point out that ground stress/buried depth is principal-control factor. Under the same buried depth other factors play more important role on permeability. |

| Keywords: | coal reservoir ground stress permeability fracture |
