Discussion and consideration on the classification management of outburst coal seam

In order to effectively prevent and contain coal and gas outburst accidents and comprehensively promote the management of the goal of "zero outburst" in coal seams, based on the domestic and abroad research results of coal and gas outburst classification and the current management measures of strengthening outburst prevention in China, the classification management scheme of outburst coal seam was put forward and analyzed in depth. The idea of non-classification of outburst coal seam and strengthening management of outburst area was determined. By using mathematical statistics, the outburst risk index of the coal seam where the serious outburst accident occurred from 2000 to 2018, as well as the data of gas pressure and gas content measured in a large number of laboratories were statistically analyzed, the classification indexes and measures for strengthening the management of outburst coal seam were put forward, so as to further refine and improve the outburst prevention management system of coal mines in China.
