...) and high temperature (250ºC) conditions. The UDS is equipped with a single cutter, a method to rotate the rock against the cutter, and a three-force-component load cell. The system incorporates a view window into the pressure vessel to allow both visual and X-ray examination of the drilling process...

... and formation of cutter roof failure. In-mine mapping of ground conditions showed an increase in roof failure in areas of high frequencies of clastic dikes. Rock pressure monitoring around clastic dikes registered the greatest amount of roof loading near the intersection of dikes with the rib. Load cells...

...-deformation) curves for each of the blocks. It was developed to provide this input. It differs from the usual uniaxial compression testing tech- nique in that the lower platen is sub-divid- ed into a matrix of individual platens each with its own load cell. The loads measured by the various platens...
