| 英文摘要 | Orebody morphology has a great influence on stability of mines. In the paper, based on the prototype of the representative metal mine, two-dimensional physical simulation model test and numerical simulation on an underground iron mine are carried out. The regulations of surface deformation and surrounding rock movement caused by underground mining for orebody with complex morphology are obtained. Results obtained indicate that surface pit expands far faster in the hanging wall than in the foot wall, and the stability of the foot wall is significantly higher than that of the hanging wall. Surface deformation significantly lags behind underground mining. Time effects of surface deformation are very obvious and theological behaviors are remarkable. The subsidence of surface and the deformation of surrounding rock increase slowly when ores between -270m and -550m are excavated owing to near steep orebody. But when ores below -550m are excavated, they speed up because the obliquity of orebody becomes smaller. |
