Fuzzy Synthetic Evaluation System Of Mine Ventilation Indexes In Dong Qu Colliery

This paper is based on XiShan Colliery Group Company's researching project for dDongQu Mine Pit Ventilation Resistance Mensuration2, applying fuzzy mathematics, system theories and the methods of statisticses, in the foundation of system evaluation principle that is thoroughly researched, put forward the system for the mine ventilation system fuzzy synthetic evaluation, make sure the evaluation indexes, its weight and subject function, establish the mathematics model of synthetic evaluation for mine ventilation indexes, make fuzzy comprehensive assessment to the mine ventilation system.The paper applys the actual data of mine ventilation resistance mensuration, combines the present condition of the mine ventilation system, analysis and evaluate the result of system evaluation, its analysis result is satisfied and basically fit to the fact.It not only provides scientific criterion for solving production plan, scientific management and right decision-making, also provides a new researching method and approach for solving problem evaluation.
