Study on Influence of Fault Structure on Laws of Gas Occurrence in Kilometer Deep Mine Based on Fractal Theory
摘要
Abstract
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.关键词
