Mining3 design, construction and monitoring of ramp and level development at great depth. As underground mining proceeds to depths approaching 1000m, the ratio of intact rock strength/induced stresses around conventional development excavations, is such that failure of the rock mass adjacent to the excavations can occur very soon after construction.
Problems in rock mechanics [and in rock engineering] usually fall in the data-limited category; one seldom knows enough about a rock mass to model it unambiguously. They then add: rock mechanics models should never be run only once; it is in the sensitivity of the results to changes in parameters and assumptions that the model is most informing.
