The paper looks at the measurement of appropriate rock properties, rock stress and fluid pressure to determine how and when failure will occur. It also examines how fluid pressure operates within the rock mass – whether through the effects of poroelasticity or directly on fracture faces. It discusses the transition between these states within the rock mass. The emphasis of the paper is on measurement rather than on modelling and techniques to get the appropriate measurements are discussed. Field cases within laminated strata are covered. }, keywords={caving}, keywords={stress}, keywords={effective stress}, keywords={fluid pressure}, keywords={permeability}, keywords={measurement}, doi={10.36487/ACG_repo/2205_95}, url={https://papers.acg.uwa.edu.au/p/2205_95_Gray/} }
