| Abstract: | The theory of coal mining subsidence, probability integration method and 3 D model of ADINA, combining the theory of subsidence empirical formula including numerical simulation is use to synthetically analyse the mining subsidence. A basic mathematical model is estab- lished after selecting reasonable calculation parameters. The results show that the comprehensive analysis of the probability integration method and the numerical simulation can accurately forecast the remaining deformation, and it is significant to forecast for future disasters and the construction of freeways which pass through the collapse of mined area. |
