摘　　要：以新汶矿区千米深井潘西煤矿为例,研究了后六采区19#煤层断层空间分布特征,运用分形理论对断层构造进行了定量化研究。结果表明:潘西煤矿研究区域内,断层构造复杂,总体呈"W"形由北西-南东向展布,对瓦斯赋存具有明显影响。分形维数能够反映断层构造复杂程度,分形维数越大,断层构造越复杂,潘西煤矿断层分形维数多数在0.7～1.6之间。分形维数大的区域,瓦斯含量亦相对较大。Taking Panxi Coal Mine, a kilometer deep mine in Xinwen Mining Area as an example, the spatial distribution characteristics of 19#coal seam fault in Houliu Mining Area are studied, and the fault structure is quantitatively studied by fractal theory. The results show that the fault structure is complex in the research area of Panxi Coal Mine, and the overall"W"shape is spread from the northwest to the southeast, which has obvious influence on gas occurrence. Fractal dimension can reflect the complexity of fault structure. The larger the fractal dimension is, the more complicated the fault structure is. The fractal dimension of Panxi Coal Mine is mostly between 0.7 and 1.6. In the areas with large fractal dimensions, the gas content is relatively large.This study has important practical application value for revealing the influence of faults on gas occurrence.
