中文摘要：

监测表明,长期采用充填法开采的大型金属矿山也会发生显著的地表变形破坏现象.为了掌握金川镍矿地下开采引起的地表移动、变形和破坏规律,借助GPS技术作为地表移动的监测手段,建立了覆盖矿区地表的GPS监测网.持续的监测数据表明,金川矿区地表最大沉降量已达2400mm左右,以现场调查与地表长期监测数据为依据,给出了地表移动的范围与特征,分析了与岩体移动、变形和破坏现象发生相关的条件和规律,并提出了一些具有预测性的观点,为工程地质-岩石力学条件大致相同矿山的工程技术人员和研究人员提供了一个有借鉴意义的实例.

英文摘要：

Backfill mining could induce noticeable ground movement when it is applied to be mining of large-scale metal orebody.The paper aims to grasp the deformation mechanism of the surface movement and destruction in Jinchuan Nickel Mine Area caused by underground mining.It uses the GPS monitoring system that is built covering the whole area.The range and the characteristics of the surface movement area are quantified using the data from the site investigation and monitoring.The condition and law that are related to the rock mass movement and deformation are analyzed.Besides,a number of predictive points of view are made.Consequently,this paper can be used as a reference for technicians and researchers when facing the mines that have a similar engineering and rock mechanics conditions as this mine area.
