The Study On Reliability And Stability Of The Ventilation System Of Lv Jiatuo Mine

The ventilation system is an important system of the mineral well assistance. It related to the personnel's life safety in the mine. The quality of ventilation system closely related to the fire prevention and cure, gas trouble, dust manage, hot harm manage and so on. Many casualties all relevant to the unreasonable and undependable ventilation system, it is practice meaning and theories value of the research on the reliability of ventilation system.From the point of view of analysis of ventilation system,the mathematical models and the relationships between reliability,stability and airway sensibility of a ventilation system are studied. The thesis make use of intelligent degree and credibility as index sign, opposite angles allied stability, credibility and Cape of branch allied branch of existence to ventilation system stability, credibility of influence carried on quantitative analysis, get Cape allied the branch be unsteady, but Cape allied branch of existence will make well ventilated the stability, credibility of the system get exaltation of conclusion.The thesis make use of intelligent degree and credibility as index sign, opposite angles allied stability, credibility and Cape of branch allied branch of existence to ventilation system stability, credibility of influence carried on quantitative analysis, get Cape allied the branch be unsteady, but Cape allied branch of existence will make well ventilated the stability, credibility of the system get exaltation of conclusion. The problem of the reliability of the mine ventilation system is also analyzed, and the value of reliability of the system is attained. And the laneways of the mine are hierarchically administered based on sensibility of failure of reliability, in order that the mine can produce safely and highly effective.
