The probability analysis of occurrence causes of extraordinarily serious gas explosion accidences and its revelation

ZHOU Xin-quan1,CHEN Guo-xin1,2(1.National Key Laboratory of Coal Resources and Safe Mining, China University of Mining & Technology(Beijing),Beijing 100083,China;2.State Administration of Work Safety,Beijing 100713,China)  
Based on the statistics and probability analysis of the occurrence causes of extraordinarily serious gas explosion accidences,revealed the new characteristics and regularity of the occurrence causes in the serious gas explosion accidences,that meaned the most serious gas explosion accidents occurred at the ordinal "safe area" with lower gas concentration in the recent years.The necessity and possibility of the prevention and control,for the serious hidden dangers induced by the dynamically state change in ordinal "safe area" to dangerous state with the unexpected gas released and the secondary disasters induced from the ordinal disasters,were analyzed.As an example for setting up the new safe guarantee mechanism with the high reliability,presented the engineering technology and management measures in the prevention and control of gas disaster in coal mines.
