英文摘要 | Based on the geological conditions, underground mining situations, as well as the status of cracks and surface deformation of Chengchao Iron, a cantilever mechanical model is proposed. The bottom-up tubular collapse in the deep rock mass causes the horizontal tectonic stress release which favors the bending fracture deformation and destruction of the NWW-trending joints. This model can explain the formation of four zones in the deep rock mass: rupture zone, the transition zone of rupture to deformation, the deformation zone, and the undisturbed zone. In such a mode, it inevitably leads to different deformation areas on the surface related to the different zones in the deep rock mass. So the mine surface is divided into four related areas: cumulative deformation area, crack-producing area, crack-extending area, and crack-closing area. As mining progresses, four zones of the deep rock mass will gradually extend downward, while four areas of the surface deformation will gradually expand outward. |
