Land Reclamation in Mining Subsidence Based on Matter Element Model

In order to obtain mining land reclamation scheme reasonably, the matter element model was proposed. The divergence which is the character of matter element model was used to design land reclamation schemes. The of land reclamation matter element model are nature state, geology structure, reclamation process, mining subsidence state, present mining condition financing. At first, the author applied the divergence of matter element to establish scheme collection. Then qualified schemes are selected preliminarily according to the known value. The following step is establishing another appraisal matter element model, which eigenvalues are land production, cost, farmer per enhancive income, ecosystem stability, biodiversity, landscape diversity. In the appraisal matter element, Shannon index reflects biodiversity and affinity analysis reflects landscape diversity. Through the appraisal matter element model dependent function between preliminarily schemes was set up. Finally, the most excellent one is selected by the optimal appraisal method. Moreover, a design process of land reclamation in Neiqiu mining subsidence was introduced. The result shows that the divergence tree method is extension and logical.
