| Abstract: | In this paper, based on physics resemble simulation and numerical simulation, gradscomposite board mechanics model on overlying strata was obtained by studying shallower coal seam mining under thin base rock in SHENDONG GROUP.Periodic weighting was analysed by the bearing wedge model, simultaneity,the mechanics of first weighting and periodic weighting were expounded. |
