Evaluation system of mineral resources economical and intensive utilization based on AHP

Under the background of the prominent contradiction between population and mineral resources reserves, it’s very important to construct a set of evaluation system to evaluate the level of mineral resources economical and intensive utilization in China.This paper stars with the concept of mineral resources economical and intensive utilization and analyzes the influences of the level of mineral resources economical and intensive utilization.The evaluation system is constructed, which includes six target layer indexes, such as standard mining and management degree, resource guarantee ability, mineral resource development and utilization level, economic benefit of mineral resource utilization, resource recycling and technical support.The system also includes twenty-one index layer indexes.The relative weight is calculated with the analytic hierarchy process.The weight of the layer relative to the upper layer from the highest to the lowest is obtained so as to calculate out the total weight of the system layer by the index layer.The verification from three typical copper mines shows the comprehensive score contrast of mineral resources economical and intensive utilization for the three mines.With the use of this evaluation system,the intensive and economical utilization level of different mines at the same time can be contrasted and evaluated in three levels of the system layer, target layer and index layer.The evaluation system is flexible and diversified in form, with certain application promotion value.
