基于可拓数学的矿井通风系统外部优化

摘要

基于目前煤矿通风系统外部优化研究不足的现状,应用可拓数学研究通风系统外部优化的不相容问题.采用计算机模拟、理论分析及现场实践相结合的方法,以评价物元、经典物元、节域物元的建立和关联度计算为基础,建立了通风系统外部优化可拓优选模型,此模型通过合格度及优度来筛选出最优方案.该模型已应用于刘东煤矿通风系统外部优化上,有效的确定了最优方案.得到的最优方案已经应用于矿井实际,不但原有矿井存在的问题得到改善,而且获得了很大的经济效益.该模型不仅能够确定出最优方案,还可以通过关联函数的正负了解各种的方案优劣程度及转化的方向.%Based on the status of inadequate research about external priority of mine ventilation system, the incompatibility topics on external priority of mine ventilation system was studied by applying extension mathematics. Using the combining methods of computer simulation, theoretical analysis and on-site practice and basing on the extension of evaluation matter, classic material, section domain objects and calculation correlation degree, an external priority extension optimization model of mine ventilation system was established. This model filtered out the optimal solution by qualified degree and priority degree. The model was applied on external priority of mine ventilation system in Liu Dong Coal Mine, and it determined the optimum solution effectively. The optimal solution was applied to Liu Dong Coal Mine, not only the problems of the original mine were improved, also a lot of economic benefits were obtained. It can not only determine the best plan, but also understand the transformation of various programs by the correlation function.
