- W2377679112 abstract "In view of features of multi-attribution,certainties and uncertainties coexisted in the optimization of mining scheme,a fuzzy matter-element model for optimization of mining scheme was established based on entropy weight in terms of safety,economy and technology.The dynamic,static,quantitative and non-quantitative factors influencing mining scheme were taken into account,and 8 indexes were selected including productivity,working face efficiency,loss ratio,dilution ratio,stripping ratio,mining costs,stoping safety and operating difficulties.During this process,the synthetic evaluation criterion weight was determined by combining the entropy weight and the decision-maker′s subjective evaluation criterion weight.The optimal mining scheme was determined by calculating Euclid approach degree(EAD) between the compound fuzzy matter-element and the standard fuzzy matter-element.The practice in Huangshaping Lead-zinc Mine shows this new procedure is effective and feasible for selecting alternatives of mining scheme,which can effectively solve the difficulty in weight allocation and make the weight allocation more reasonable.The Euclid approach degree(EAD) of the mining methods in Huangshaping Lead-zinc Mine are respectively 82.1%,80.4%and 68.9% based on this model,so the first mining scheme is selected.It can be seen this model proposed a new idea for comprehensively evaluating mining scheme." @default.
