Abstract:
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.
