| Abstract: | Through analysing the affection by underground mining and deformation rift regularity of loess cover,this paper presents a method to contral or abate the destruction due to the surface deformation rift by means of mining method and technology so that under the protection for surface structure, we can extract the caol under buildings,railways and water bodies as more as possible. |

| Keywords: | loess cover deformation rift coal under buildings railways and water bodies |
