Analysis on land reclamation in Niuxintai coal mining subsidence area

In order to solve the non-renewable resources after the coal by large-scale mining, coal mining subsidence on the destruction of the normal use of land and environmental problems, this paper did in-depth research, development and utilization of renewable resources and the benign development of the society of land resources. The nonlinear least square fitting function in MATLAB was used to calculate the surface movement deformation parameters in the coal mining subsidence area, and the probability integral method is used to forecast damaged land well versed in mining coal mine. The subsidence and land reclamation of subsidence characteristics are discussed in this social background, land reclamation project instance analysis, and subsidence area land reclamation project practice and implementation. Land reclamation in mining subsidence area research application and analysis on the basis of engineering practice, and to carry out actively under the existing technical and financial support for the mining area land reclamation of mining subsidence area research, and project implementation has certain reference value and practical significance.
