4、od, experimental analysis and computer simulation, the comprehensive research methods etc. The outburst prevention technique by cutting through outburst coal seam is made a sufficient study, and the whole thought of the outburst prevention technique is put forward. In the aspect of theory, combined
5、with coal and gas outburst, the mechanism of the study of the main physical and mechanical performance coal seam gas flow theory are studied. Based on solid flow coupling theory, auxiliary shaft of Zhuji coal mine is taken the research object, and the mathematical model about coal and gas outburst i
6、s set up. In field measurement, the technology of multi-step hole sealing is used on hole sealing. the coal seam gas pressure is determined by gas water separation device, the measurement of pressure measuring by separating source, the measurement of gas source water pressure. Then integrated regional “quaternity“ outburst prevention measures and the treatment of outburst accidents are discussed. The mathematical model of coal and gas outburst is establis
