THE DYNAMIC PROCESS ANALYSIS OF STRATUM MOVEMENT INCLINED SEAM MINING
The overburden strata movement and surface subsidence are a complicated dynamic process. In the process of stratum movement and deformation, the rock mass has the property of rheology. At the same time, strata have the different deformations in time-space processes for the laminar combinatorial structure of the rock. Based on the theory of thin plate flexure and rheology, the time and space process of the strata movement and surface subsidence are studied. The related formulas are derived to calculate the surface subsidence and time coefficient, which also provides a new method to predict dynamic process of surface subsidence.
