Research on safety input research model for preventing coal gas explosion

AbstractThe paper dedicates to analysis of the main reasons of the mine gas explosion accident through the statistics of mine gas explosion accidents at home and abroad. The inner logic relationship between accidents and the causes of accidents is explored by using fault tree analysis method. The relationship between the safety input and accident occurrence frequency is discussed, and the function relationship between which is established with GongBo curve. On the basis of settled safety investment, using the influence of basic event on top accident's occurrence probability, the safety input optimization allocation model is established for the goal of making the accident occurrence probability minimum, which can be solved by using Lingo software based on historical data
