"The problem of this investigation involves the determination of the coefficients of thermal expansion of mine rocks, and the relationship of porosity, permeability, and consecutive temperature changes to the permanent elongation of those rocks. One of the major problems in mining today is that of the analysis of the action of exposed mine rock under changes of temperature. The immediate cause of a fall of ground in a mining excavation is due to the fact that some part of the mass that falls has been subjected to a stress beyond the strength of the rock. The question arises as to what changes occur in these exposed rock masses to cause the rock to fall"--Introduction, page 1.
