Abstract

With the development of outburst prevention technology and the improvement of management level in China's outburst mines in the new era, the classification of outburst coal seams has important guiding significance for the further refinement, improvement, and enhancement of China's outburst mine gas prevention and control system. Therefore, it is necessary to further classify outburst coal seams. Through the analysis of outburst accidents with deaths of more than or equal to 3 people since 2000, a large number of basic gas parameters in the laboratory, and previous research results, in-depth discussions were conducted on the methods and basis for classification of outburst coal seams, as well as related issues such as judgment rules and critical values of indicators. It is proposed to divide outburst coal seams into two levels: ‘general outburst coal seams’ and ‘severe outburst coal seams’. A classification method for outburst coal seams based on outburst strength has been established. The judgment rules for severe outburst coal seams have been established, including the amount of coal thrown out S, the amount of gas emitted per ton of coal Q0 and the number of outburst times N. The critical values of the judgment indicators have been determined. Through the research, it will provide an important basis for the determination of mining procedures, outburst prevention planning and mining replacement planning, etc.
