Quantitative research to coal mine structure acting on coal and gas outburst

Abstract：In the research to the coal and gas outburst of the 12th Coal Mine of Pingdingshan mining area, it has analyzed the relation between structure and outburst.It has first used the mathematics methods in the structure_complexity area, quantitatively analyzed the structure factors which lead to outburst, improved and simplified the formulas of computing the structure_complexity coefficient.According to the actual condition, it has put forward the determinate principles of structure_complexity degree leading outburst, marked off the critical value and gas areas, and acquired a good result.
