| Abstract: | The paper took Haizi coal mine of Huaibei city for prototype.According to the theory of similarity,the similar material simulation experiment was used to research the strata sinking and horizontal movement of gently inclined working face in the post-harvest.The strata and the surface movement parameters have been obtained.The study can provide the theory basis for the promotion and application of gently inclined seam mining technology.It also has practical value for guiding the Haizi coal mine to reduce mining damage and set the protection pillar. |
