In deep mining, roadway surrounding had large deformation, high stress, broken degree higher characteristic, the stress and displacement which in shallow coal seam, rock, in the elastic-plastic analytical solution exists much shortage. Aiming at the existing problems, at home and abroad on some characteristics of deep surrounding rock had done the thorough research. In this paper, based on the formula Kastner equation and the theory of Moore strength, the reasonable consideration of the important characteristics of rock burst intensity attenuation and volume expansion, roadway surrounding rock elastic-plastic stress and displacement analytic solution was established.
