Study on surface subsidence forecasting system of nearly flat coal seam mining

Against the features of near level seam coal mining subsidence,the random medium theory is applied to make a predict research,considering the factors of mining geology and the impact of mining technology,a reasonable trade-off parameter predicted value,combined with real exploitation example,the near level coal mining subsidence forecast system is coded,this system realizes a series of functional modules,using this system can accurately and intuitively predict the development and the situation of near level coal mining subsidence in recent,and the predict results are practical,it is beneficial to make an analysis about the overall surface deformation.
