Study On Safety Assessment And Optimization Of Mine Ventilation System

Mine ventilation system is a subsystem of the mine production，It attached to themain system，but also restriced the mine production. The pros and cons of the mineventilation system, directly related to safety in mine production and economic benefits.Therefore, it must be the correct assession of the mine ventilation system.In this article, start form the definition of the mine ventilation system, from threeaspects of the safety, feasibility, economic, to determine seven indicators of coal mineventilation: Ventilation power, Ventilation network, Ventilation facility, Ventilationquality, Ventilation disaster prevention and resilience, Ventilation scientificmanagement, Economical and reasonable ventilation. Then detail of the sevenindicators.In this paper,the author selected from the detail indicators, which can directimpact on the value of indicators and has a clear physical meaning and independentindicators of the quantitative criteria. To establish the appropriation of the quantizationfunction, the author calculates its evaluation value.Established a perfect system of mine ventilation system evaluation, combination ofanalytic hierarchy process in systems engineering, In principle of prominented the mineventilation system is safe, reliable, and the economy. The author determines the weightsof ever indicators. Based on the weight values and the evaluation values, Calculate theevaluation values the total score of the mine ventilation.According to the proposed ventilation system optimization, selected the actual caseof mine optimization.The use of established evaluation system to determine theparameter values. The calculation of the mine ventilation before optimization andoptimizations of the mine ventilation has been proposed.Discovered the merits andshortcomings of the various options. Determine the optimal solution and can begeneralized conclusion.
