Abstract
ABSTRACTIn order to study the gas occurrence regularity and the main controlling factors of Panxi Mine, gas parameters of the mine were determined through the combination of field survey and experiment, and the distribution regularity of gas content in coal seam strike and dip was analyzed. Besides, the fault structure was quantitatively researched based on the fractal theory. The experimental results show that the fractal dimension of the mine mostly ranges from 0.7 to 1.6. The fault structure becomes more complex with the increase of fractal dimension, and the gas content in the region with a larger fractal dimension is higher. The fractal dimension of fault can reflect complexity of geological structure of the mine. The research is targeted to the prevention and control of gas accidents in Panxi Mine, and it has important theoretical and practical significance for promoting safety production and gas development and utilization in coal mines.
