Study On Many Wind Wells Mine Ventilation System Stability

This article through much wind wells mine ventilation system stability mechanism analysis and research on the careful well mine ventilation system analysis, the paper analyzes fan joint working stability of mine ventilation system, this paper analyzed the fan system more joint operation of the mutual influence and reviewing several different conditions in the network wind flow stability mechanism; Will more wind wells mine ventilation system stability as a complicated system engineering, the ventilation system of ventilated effect, technical performance and economic indicators make evaluation, analysis, research and evaluation of each factors to influence the stability of the system size, degree and range, not only to the normal production period ventilation system stability factors dig deep, but also to catastrophe possible not stable period are analyzed, and the establishment of the mine ventilation system work well not stable for the top of the events of the fault tree; More on wind wells mine ventilation system stability problems on the evaluation system research, the experts and combining with the evaluation method of wind wells are mine ventilation system stability evaluation index, and build the membership function of each index; The experts evaluation by using ahp and combining with the principle to determine the relative importance of each index degree, the analysis of the relative importance of each index get weight values; Using fuzzy comprehensive evaluation method, the more specific wind wells mine ventilation system stability evaluation, and development of specific stability evaluation intelligence software, for example verified the application effect of software. The research results to find out how well the wind caused by mine ventilation system unstable factors, so as to make different coping measures to ensure that in the new. period the stability of mine ventilation system, ensure the coal mine safety and highly efficient production has the important practical significance and theoretical value.Figure23table20references47...
