摘要
为解决金属矿山井下空气品质综合评价困难的问题,基于物元模型理论,选取CO、NO2、H2S、SO2及粉尘5种主要有毒有害物质浓度标度指数作为矿井空气品质评价因子,建立金属矿山井下空气品质综合评价的物元模型,依据行业标准得到评价所需的经典域和节域,根据测得的各有害物质浓度并转化为标度指数得到待评物元,在此基础上建立关联度函数,并结合相应权重得到关于井下空气品质标准等级的关联度,最终求出评价结果。应用该模型对某金属矿井下空气品质进行综合评价,结果与矿山实际情况相符合,为解决金属矿山井下空气品质综合评价的复杂性与不确定性提供了一条新思路。
In order to solve difficulties of comprehensive evaluation on underground air quality in metal mine,the concentration indexes of CO,NO2,H2 S,SO2and dust as the the evaluation factors of air quality were selected,and the matter element model was built based on the matter element model theory.Classical domain and joint domain that were required in evaluation were obtained according to industry standards.And the evaluated matter element was obtained in terms of the measured concentrations of harmful substances and transferred scalinf exponents.On this basis,the correlation function was established,and the correlation degree of air quality standard grade was received combining with corresponding weights.Finally,the evaluation results were obtained.Comprehensive evaluation on underground air quality in a metal mine was conducted by this model,and the results were accorded with the actual situation of mine,which provided a new idea for solving the complexity and uncertainty of comprehensive evaluation.
