Abstract:
This paper introduces the concept and classification of mining solid wastes,and also illustrates the importance and necessity of the recycling utilization of mining solid wastes as normal resources.The present status of the recycling utilization of mining solid wastes is discussed;and the two major directions of the utilization are also analyzed:the recycling of the useful components and the direct utilization of mining solid wastes,the latter of which includes their uses in building materials,mining filling materials,and agricultural soil improving agents.The 5 critical issues concerning the recycling utilization of the mining solid wastes,which are respectively as follows:① the weak consciousness of the recycling utilization of mining solid wastes;② the imperfect of the regulating laws;③ the unclear present status of the recycling utilization;④ the unsatisfactory lagging-behind techniques of the recycling utilization;⑤ the lack of incentive mechanism and/or compulsory measure s,are probed in details.Meanwhile the corresponding countermeasures,which are respectively as follows:① raising consciousness of the recycling utilization of mining solid wastes;② perfecting the regulating laws;③ investigation and evaluation of the mining solid wastes;④ promotion of advanced techniques of the recycling utilization;⑤ perfecting incentive mechanism and/or compulsory measures,are also proposed so as to turn the mining solid wastes from “ecological burden” to “resources wealth”.
