Study On The Laws Of Parameters Of Surface Movement And Deformation On Feicheng Mining Area

The study on the laws of subsidence due to mining is of great significant to the country economic development and improving people's livelihood. The environment and the balance between the building and construct of the earth's surface has been broken due to the land subsidence caused by mining. Predominating the laws can not only minimize the loss, also make a correct forecast for the status during the mining.Based on the material of mining subsidence on Feicheng mining area, by using advanced theory and method of ground movement models and parameters identification and the characteristics of observed data, the parameters of the rock strata and surface movement in condition of the special geological mining were determined and the contour map of the deformation were protracted in this paper. The map can be the basis for mining subsidence forecasting and controlling.Using the method of regression analysis and MATLAB software, the formula were set up based on studying relations between parameters of rock strata and surface movement due to mining and geological condition. The dependability of the formula has been verified, and it can be reference to the similar conditions.
