| 摘 要： | 针对甘肃金川龙首矿露天转地下开采条件下的边坡岩体变形、破坏和稳定性问题,在矿区大范围内建立了地表岩移GPS监测网络。持续5.5 a的监测结果表明：地下开采已经引起地表大范围的岩体移动和变形。矿体上盘地表监测点累积最大水平位移量达853.1 mm,最大三维位移量达951.7 mm;矿体下盘地表监测点累积最大水平位移量达7...

| Abstract: | According to the practical state of rock mass movement,deformation and fracture induced by underground mining,a systematical GPS monitoring network was established on the ground surface of the mine.Based on persistent monitoring in the last five and half years,the results show that a large-scale subsidence trough has been developed after the transition from open pit mining to underground mining.Almost all coordinates of the monitoring points are being changed constantly.In the upper surface of the ore body,... |
