The Establishment And Application Of Safety Evaluation System In Coal Mine Ventilation Based On Infopmation Entropy

In this thesis, the basic safety situation is analyzed about coal industry, it states the great signifance of work safety and gives the urgency and necessity of developing safety assessment in mine ventilation system. The safety assessment aims at finding problem,eliminating hidden dangers in mine ventilation system,adjusting and reforming system, optimizing design of ventilation system, working out scheme of preventing and disposing the accident. The ventilation and safety management are gived in spot by safety assessment.This thesis introduces development and application condition in present about safety assessment technique and its software. It puts forward the research project of the safety assessment based on information entropy according to the existing problem in selecting index and evaluation method. The study results were applied in the practice samples, and the prosoective results were attained.
