微震监测和三维激光扫描联合监测技术在山达克南矿体扩帮边坡监测中的应用

Application of microseismic monitoring and 3D laser scanning at pit wall expansion mining of Saindak South Orebody

露天矿边坡监测对矿山安全生产起着重要的保障作用,但传统的边坡监测手段单一,监测结果不能很好地表现边坡的整体变化。微震监测和三维激光扫描技术的联合运用,能监测到某个边坡整体变化趋势,以及爆破、开挖等施工扰动对边坡的影响。实践表明,联合监测技术对大范围的高陡边坡监测,尤其是对露天矿深部强化开采的高陡边坡监测中有着重要的指导和实践意义。

Open-pit slope monitoring is of vital importance for mine safety,and traditional monitoring techniques are limited to show the overall change of slope stability.The combined application of microseismic monitoring and3 Dlaser scanning can monitor the trend of overall change,as well as the effect of engineering disturbances such as blasting and excavation on slope stability.Practice indicated that these techniques provided essential guidance to slope stability monitoring of high pit wall,especially pit wall deep below with expansion mining practice.
