主　　题：open-pit ground movement long-term GPS monitoring deformation analysis 

摘      要：To trace the potential hazards of open-pit slope in Longshou mine,global positioning system（GPS） is applied to monitoring ground movement and deformation induced by transition from open-pit to underground *** long-term monitoring from 2003 to 2008,huge amounts of data were *** results show that large-scale ground movement and deformation have occurred in mining area,and the movement area is *** displacement boundary of settlement trough is 2.0 km long along the exploratory line,and 1.5 km long along the strike of ore *** monitoring results basically agree with the practical deformation state of open-pit *** is indicated that the long-term GPS monitoring is an effective way to understand the mechanism of ground movement and deformation in mine area. 更多
