One Ventilation And Three Preventions Safety Management Evaluation System Research And Application For Mine

Ventilation is to prevent gas and coal dust, fire disaster of three, One-ventilation andthree-prevention safe production of coal mine working is heavy, so constructing thereasonable and effective one ventilation and three prevention safety evaluation system to coalmine safety production is crucial.In view of coal mine "one ventilation and three prevention" system safety problems, inorder to mine safety as the research object, through the coal mine gas, ventilation,spontaneous combustion, dust and multiple monitoring data and the impact factor of thecollection, will one ventilation and three prevention work related to safety of various factorsby refinement, analysis, establishing safety evaluation index system.Then using the fuzzycomprehensive evaluation method, the risk factors on security degree of membership gradecondition as the basis, calculate and determine the weight distribution of each index set,establish the fuzzy multi-level comprehensive evaluation model, which will be mine complexproblem layer is divided into simple questions, make the qualitative safety quantitativeevaluation possible.Finally, in order to evaluate the model as the basis, using C/S architecture,the NET development platform the research and development of coal mine one ventilationand three prevention safety assessment system, give full play to the computer calculation ofefficient, friendly interface, convenient operation advantage, the original complexmathematical calculation evaluation process package, make one ventilation and threeprevention safety evaluation system become more suitable for coal mine safety evaluation ofengineering and technical personnel at the scene using a security evaluation tool.In the last part of the field test, application of one ventilation and three prevention safetyevaluation system for JianGou Mine one ventilation and three prevention work for safetyevaluation, and according to the evaluation results, the mine one ventilation and threeprevention problems in the security system of the scientific analysis, proposed therationalization proposal.
