Coal-gangue Comprehensive Evaluation of Xilutian Coal Mine of Inner Mongolia Pingzhuang Energy Resources Co., LTD

摘要

The coal gangue is one of resources,which will be boosted in comprehensive exploitation and high effective utilization.During more than 50 years mining,large numbers of gangue were discharged by Pingzhuang Xilutian Coal Mine,estimating that the accumulative amount of coal gangue will reach about 36.56 million tons to the end of Mine closed.How to utilize the coal gangue and make full use of it,is one mainly question for the mine to face.Based on a large related information collection,the index of the coal gangue comprehensive utilization of the mine was measured in this paper.Through the comprehensive analysis of the results of chemical examination,the comprehensive evaluation has been had for the coal gangue comprehensive utilization direction,which suggests that the main utilization direction of coal gangue include using it to generate electricity,or to make bricks or to be chemical raw materials.The rare elements of germanium (Ge),vanadium (V) and radioactive uranium (U) in the coal gangue are failed to reach the ore mining grade and can not be utilized for the time being.
