Research on Optimization of Gas Explosion Hazard Evaluation Index*

摘要：

Gas explosion accidents in coalmine keeps interacting the safety status in China. Comprehensive targets of safety evaluation should be taken into account so as to identify and assess those hazards. This paper revised the division of three types of hazard in coalmine based on the Three Type Hazard theory, and set up a preliminary evaluation index system of gas explosion, including three types 33 terms. Data on spot was collected, and the index were reduced to 19 terms based on Rough Set. Software Rosetta was used for simulation through gas hazard evaluation to test the reduction was reasonable by Neural Network. It was proved that the accuracy greatly improved in hazard evaluation network simulation after Rough Set reduction as well as convergence rate accelerated, which showed feasibility of this optimization method. So it played a certain positive role in improve accuracy and real time of hazard evaluation system.
