Research On Mineral Technical And Economic Evaluation Of Integrated Exploration Areas

As of November 14,2013,109 pieces of national strategic integrated exploration areas has been set up,with a total area of about 505,500 square kilometers.All the integrated exploration areas distribut in 25 provinces,and the main types of minerals are shortage or bulk-type minerals.As the head of the prospecting breakthrough,integrated exploration areas have achieved lots of achievements.With the promotion of integrated exploration,it's imperative to promote the mineral technical and economic evaluation of integrated exploration areas.Guided by the comprehensive evaluation of regional mineral resource theory,this paper builded a index system of mineral technical and economic evaluation of integrated exploration areas from five aspects including market demand,mining geological conditions,socio-economic conditions,environmental constraints and organization.On the basis of the AHP and fuzzy mathematics,this paper established the fuzzy hierarchy comprehensive evaluation model.This result is a score,which can reflect the integrated exploration areas more intuitive,eventually be able to be sorted.And this paper selected laizhou-zhaoyuan gold integrated exploration area in Shandong provinces for the empirical research.The results showed that it's feasible and valuable of using the fuzzy comprehensive evaluation method to evaluate the integrated exploration area.This article provides some ideas and reference for comprehensive evaluation of integrated exploration areas.It also provide certain reference for construction,optimization and adjustments,social investment and new selection of integrated exploration areas.With the development of the evaluation,the evaluation index system still needs to be further perfected.With the change of the economic social and technical conditions,integrated exploration areas need to continued follow-up evaluation.
