Abstract：By statistical analysis of the data of china coal -gas dynamic disasters accidents in the latest 12 years, basic characteristics and regularity in these accidents were shown , such as the decreasing fluctuate tendency of the number of total accidents and deaths , the increasing proportion of occurrence and deaths in the larger accident and the above , and the increasing number of deaths in single accident.Based on the investiga-tion report of major accident and the above in coal -gas dynamics disasters during 2010-2012 , and on the a-nalysis of the gas explosion case for direct occurrence causes of the ignition source , the regularity of which e-lectromechanical occurrence factors account for 57.14%was found.the incentive control of electromechanical occurrence factors of the ignition source is the effective way to curb coal -gas dynamic disasters accidents and to prevent accidents to expand.
