Abstract

"The problem involves studies of the mechanical properties of rocks and was undertaken in an attempt to determine practical data that will help in estimating the supports required to maintain the roofs of mines during and after mining operations. One of the most important problems in mining today is that of the analysis of the action of mine-rock under stresses. From such an analysis in any given mining venture it should be possible to obtain cheaper methods of mining because the supports necessary to maintain the walls and roof of an excavation may be determined on the basis of how the rock will act under stress. That is, whenever an excavation is made, the roof and walls are under stress, and must be maintained against failure inasmuch as the support originally given by the materials which came from the excavation has been removed"--Introduction, page 1.
