Research On Keys Contents In Land Reclamation Project Of Underground Metal Mining And Empirical Study

A great deal of land especially the arable-land had been destroyed by the mining, which sharpens the conflict between human being and the land.In order to strength the work of land reclamation,from 2007, Ministry of land and Resources started to use land reclamation project and evaluation principle. 3 years pasted, it did not work well for the disuniform evaluation and low level statement, especially in metal minming reclamation project which Immature technology in the prediction of land destruction, land reclamation methods and reclamation funds .It is difficult to meet the requirements of Land Department. In order to solve the problems above, the article makes a deep and systemic research on the land reclamation project of matel minming evaluation standard and statement request, as well as the key contents, which makes a big sense in improving land reclamation project statement and itself. Main ideas of this article state as follows:Land and Resources issued "Document No. 81".Through the "No. 81",I analyze the requirements of land reclamation quantitatively and qualitatively in demand.Whereas analyze the key-contents of land reclamation project in accreditation by experts. Then by comparision between metal mines and coal mines,with the help of analysis in the form of land destruction ,analysis the specialist of the form of land reclamation , forecaste the land-destruction by metal mining.We can make the conclution of the evaluation of land suitability,methods of land reclamation,funds of land reclamation.this article take Gao Cheng Lead and Zinc mines in GuangDong Province as an example indicate that:we can't use the methods of Probability integral when we forecast the destruction made by metal mining in land reclamation project. we should consider the Subsidence;Measures for land reclamation in Land suitability。It includes not only the site conditions but also the contaminant barrier and the selection of the appropriate vegetation which can prevent human away from heavy metal pollution Then the funds must contain the risk capital which should acquired by quantitative and qualitative calculate,Etc.
