Missing pages. / This thesis is in the area of engineering theory. It is concerned with the combining of existing scientific theories into a rational hypothesis for predicting the loading of pillars. Hitherto, this has only been possible in a very crude way and only for horizontal workings. Analytical work to predict pillar loadings for long mining zones in elastic ground produces equations which include, in the form of dimensionless parameters, the significant geometrical and material-properties affecting pillar loading. Additional analytical work demonstrates that various arching and plastic theories are unlikely to be of any use in this problem. [...]
