| Abstract: | In the paper, we probed into some facts affecting the shape of the self-sustaining structure of host rock around drift by means of the lilinite element calculation and the lightbounce simulation. In order to bring forward the proof of choosing suitable supporting manner, we point out that the changes of some imfluent facts,such as the decpth of drift lying , the coefficient of side pressure, the shape of drift and crack in rock, have an effect on the circle of concentrating stress. |
