Research on Numerical Simulation of Mining Subsidence

摘要：

The strip mining method is proposed to prohibit overlying strata and surface moving. The law of displacement and deformation damage of overlying strata and surface which is a sophisticated process of physical and mechanical dynamics is analyzed in theory. Based on the actual project data, the law is obtained by the numerical simulation with FLAC3D. Moreover, the strip reasonable mining method and interrelated parameters is presented according to the specific geology and mining conditions of coal. It is proved that the strip mining method can avoid geological damage effectively for overlying strata and surface movement in practice.
