520 | 3 |a"This research work on pillar loading is in what might be described as the area of engineering theory. As such, it is concerned largely with the combining of existing scientific theories into a rational hypothesis for predicting the loading of pillars. Hitherto, this has been possible only in a very crude way and only for horizontal workings using the tributary area theory"--Abstract, page ii. |
