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GP S技术作为地表移动的监测手段,建立了覆盖矿区地表的GP S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。
鑑測錶明,長期採用充填法開採的大型金屬礦山也會髮生顯著的地錶變形破壞現象。為瞭掌握金川鎳礦地下開採引起的地錶移動、變形和破壞規律,藉助GP S技術作為地錶移動的鑑測手段,建立瞭覆蓋礦區地錶的GP S鑑測網。持續的鑑測數據錶明,金川礦區地錶最大沉降量已達2400mm左右,以現場調查與地錶長期鑑測數據為依據,給齣瞭地錶移動的範圍與特徵,分析瞭與巖體移動、變形和破壞現象髮生相關的條件和規律,併提齣瞭一些具有預測性的觀點,為工程地質-巖石力學條件大緻相同礦山的工程技術人員和研究人員提供瞭一箇有藉鑒意義的實例。

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.
