Application And Study On The Safety Appraisal Of The Mine Ventilation System

As one of important production system, Mine ventilation system play an extremely important role on maintaining mine safety production, whether a mine ventilation system is good plays an important role on saving energy and reducing the cost and anti-disaster ability, and it is the safeguard system of mine safety production. So judging the safety of a mine ventilation system is significant. Judging a mine ventilation system, we must establish a reasonable and effective method to evaluate mine ventilation system.The central work of the evaluation lies in the evaluation of the security and stability of the ventilation system of mine. On the basis of deep analysis the previous mine ventilation system target, the author used the method of comprehensive evaluation and fuzzy comprehensive evaluation, building up a comprehensive evaluation of the ventilation system. It is the main idea of this essay to assess each index respectively and to achieve comprehensive evaluation both qualitatively and quantitatively. The first part of this essay firstly discusses the hazard theory, identification method and general program of safety assessment, based on this, the author analyzes comprehensively the hazard factor of mine ventilation system, by FTA and from four factors of man-machine-environment-management; the second part primarily establishes the system of cecurity index evaluation in the ventilation system of mine; the third part protests the theory and speculation of how to evaluate the ventilation system using the fuzzy comprehensive evaluation. Finally, it gives the applied examples based on the method of comprehensive evaluation of mine.
