Risk Analysis of Brittleness on Sudden Accident System and Its Application to Coal Mine
Hui Wang · Systems Engineering · 2007
Some certain chanciness are existing in the coal accidents,and inevitabilities which are represent on the risk factors of coal mine system also do.Using entropy theory,authors quantify the risk entropy function base on the probability of the accident occurrence,causing the severity degree for coal mine safety system and the un-control degree,meanwhile,the characters of risk entropy function according to entropy function are discussed.Moreover,the problem of gas explosion is key issue,the system level,event level and factor level have been considered,and the relationship of different levels,which contain inside and between levels,also have been analyzed.Moreover,the factor sets of system collapse are found;and the risk entropy of gas explosion on coal accident system would be concluded based on the risk entropy function.
