Abstract
This paper explains a rock mass deformation modulus measurement conducted in a cross cut at Pongkor underground gold mine, where there was an active stope underneath the cross-cut. It is revealed that the resulted rock mass deformation modulus was controlled by the stoping progress. The larger the dimension of the underneath stope, the higher the rock mass deformation modulus obtained, which was due to the higher induced stress in the location. There was a 20-30% increase of rock mass modulus of deformation when the stope was advanced vertically from one mining slice to two mining slices, where the height of the slice was four metre. Keywords: Rock mass; modulus of deformation; underground mine
