【Abstract】 The overburden strata movement is a complicated time and space process. In the light of rheology theory and combinatorial movement theory ，the time and space process of the strata movement and the development of separate layers are studied. The related formulas are derived to calculate the bending deformation of control strata and the width of large cracks.更多还原
