| 520 | 3 |a"Part I of this research report gives some simple analyses and establishes some guidelines for designing support for hard rock slopes. Part II describes the installation of a trial support system and gives a breakdown of construction costs. Part III considers the design and costing of support systems for some hypothetical rock slopes. It is shown that the potential profits per linear foot of pit wall, obtained by using artificial supports to safely increase the slope angle, may be optimized"--Abstract, page iii. |
