摘要
金属矿山地下开采引起地表塌陷已经成为一种主要的矿山地质环境问题.地面塌陷受多方面因素影响,各因素相互作用使得金属矿山地表塌陷形成机理复杂.本文以大冶铁矿东露天采场地面塌陷为例,从采场地质环境、矿体特征、采矿方法、崩落角、地面塌陷的形式等方面,综述了地面塌陷的特征,并探讨了地面塌陷的形成规律,该研究为矿山地面塌陷的成因及控制对策研究提供了帮助.
Surface subsidence area caused by underground mining of metal mines has been a main problem for mine geological environment. The influence factors of surface subsidence area are in many aspects, at the same time, the interaction of each influence factors make the mechanism of surface subsidence area of metal mines be more complex. Taking surface subsidence area of east open-pit in Daye iron mine for example, this paper summarized the characteristics and analyzed the law of surface subsidence from the mine geological environment, characteristics of ore body, mining method, angle of collape, shape of surface subsidence area. This research offers help for the study of mechanism of surface subsidence and control countermeasure
