| Summary |
"The theories of ground failure in massive rock with special reference to the problem of the mechanics of block caving were studied and evaluated. The mechanics of arch or dome formation underground were studied quantitatively using the Voussoir arch theory. The effect of shear stress on the arch stability was considered and found to affect the system only when the arch height increased beyond certain limits. A theory of the mechanism of ground failure in an undercut block using the dome theory was advanced. Photo- elastic model studies were used to support the conclusions reached"--Abstract, leaf i. |
