Uranium Mine Ventilation System Reliability Management And Practice

As one underground mine ventilation system of eight ordinary mining system, the reliability of the normal production and life safety of underground mine personnel plays a vital role. Because uranium ore contains large amounts of exhaust ventilation radon and radon daughters, uranium ore dust and radioactive aerosols radioactive hazardous substances, to bring great harm to mine safety, mine ventilation is the most important means of reducing radon. Therefore, the study of uranium mine ventilation system reliability for ensuring mine production safety has important application prospect.First, analyze the impact of uranium mine ventilation system reliability main control node, mine ventilation network subsystem reliability, Mine Main Fan subsystem reliability, mine radioactive contamination control system reliability, the reliability of mine ventilation system management, etc.,and system analysis was carried out separately.Second, build underground uranium mine ventilation system evaluation system. The reliability of the uranium mine ventilation system into the mine ventilation network subsystem reliability, Mine Main Fan subsystem reliability, the reliability of the control system of mine radioactive contaminants, four-level evaluation of mine ventilation system reliability management, etc., and then on this basis, were subdivided into 20 two evaluation index system, and so the establishment of the mine ventilation system reliability evaluation system.Again, analytic hierarchy process analysis of the major uranium deposits of small ventilation system reliability relative weight of each index,taking into account the uncertainty of the ventilation system reliability and flexible management, effective and practical method to determine the use of fuzzy comprehensive evaluation method as the ventilation system reliability evaluation.Finally, taking a certain uranium mine as an example, to carry out the whole network of ventilation, ventilation structures, ventilating roadway oflocal facilities, the main ventilation equipment and uranium mine ventilation reliability management case analysis, find out the existing problems and the insufficiency, proposed rectification corresponding measures for improvement, the uranium mine ventilation system reliability, has important application prospect to improve the safety in production.
