Fuzzy Synthetic Evaluation System Of Mine Ventilation Indexes In Yaoqiao Mine

In recent years, frequent accidents seriously hampered coal production, brought to the state and the individual life and property damage. According to the survey, most of the coal mine accidents have imperfections have a direct relationship with the mine ventilation system. Mine ventilation is to create a normal production environment and safety conditions, is fundamental to the basic mine safety protection. From the perspective of the reasonableness of the ventilation system to prevent accidents from occurring, the paper studies the application of fuzzy evaluation method of ventilation systems, ventilation equipment, the establishment of a factor, mine disasters, security management, ventilation, Five safety evaluation index systems to determine the index quantitative method, and the evaluation level quantized. By building evaluation mathematical model of the mine's ventilation system evaluation. In practical applications, the Yaoqiao mine ventilation system security level of the comprehensive scientific evaluation, the conclusion that the mine safety level. Ensure the rationality and stability of the mine, to prevent the occurrence of the disaster has provided scientific guidance. The actual application shows that:the use of fuzzy comprehensive evaluation method for mine ventilation system for safety evaluation, qualitative indicators can be quantitative, objective and reasonable evaluation information processing uncertainties, the evaluation results are more reasonable and reliable, scientifically valid, in order to better actually used in coal mine safety production enterprise, production safety has played a guiding role.
