Abstract:The seam of coal and gas outburst danger zone controlled by faults zonal distribution. The geological and topographical conditions of Guizhou are complex. The faults in the mines are irregular. It is difficult to use traditional mathematical methods to accurately quantify its description. In this paper, the fractal theory Ida fault structures within the coal and gas outburst in effect, can fully and accurately quantify the expression of faults and gas outburst relationship. By comparing different types of faults on scales outburst control, you can highlight the formation of a more reliable predictor.
