Abstract
Pongkor is one of the underground gold mines in Indonesia which applies the cut and fill mining method. During the mining, the stability of mine opening is one of the factors deciding the continuity of underground mining process. Due to mining activity, stresses around the mining area will be redistributed, and in some condition they may lead to a failure on the stope. To avoid such failure, it is important to monitor the deformation and understand the stress redistribution effects on surrounding rock mass as the mining activity proceeded. A borehole extensometer was installed in the ore body to monitor the rock mass displacement, and a 3D model of the mining sequence was made to understand the stress redistribution in the surrounding rock mass.
