| 摘 要： | 以华北地区柳林和安阳试验区为例,综合多种统计数据和测试成果,对煤层的渗透性及主要地质控制因素进行深入研究和探讨。研究表明,控制煤层渗透性的主要地质因素为割理的发育程度,其次为有效地应力、外生裂隙和煤体结构等。而煤的变质程度及镜质组含量又制约着割理的发育。

| Abstract: | Based on the study of pilot areas of Liulin and Anyang in No rth China,the coal reservoir permeability and main geological controlling factors deeply researched.The results show that the development degree of cleats is the major controlling factor,second is the effective stress,exokinetic fractures and the coal structure,but the cleat development is controlled by coal rank and vitrinite content. |
| |
| Keywords: | coal seam permeability fracture coal structure effective stress |
