Sommaire: The mechanical aspects of cable bolt failure are considered from the point of view of properties of grout and cable, as well as of the rock in which it is anchored. The results from recent investigations made in-situ as well as in the lab are combined and presented with reference to other work done in the area. An attempt is made to stimulate the thinking along these lines so as to initiate further research which may enhance the design of cable bolting as it applied to mining operations.

Sommaire: In this study, the authors investigated the stabilities of slopes cut predominantly into Trenton limestone in a large quarry in the Montreal region. Analyses of the bench and pit walls indicated that small-scale toppling, ravelling, and wedge failures are the most likely modes of instabilities. Because most of the joints dip steeply, however, the conclusion was made that relatively high walls could probably be justified.
The field investigations were supplemented with the determinations of...

Sommaire: Carbon addition in the oxide pelletizing process is a big concern at the Sidbec-Normines pelletizing plant since 1976.
Laboratory pot-grate testing carried out before the initial start-up of the Port-Cartier plant indicated that the nominal pelletizing grate capacity could be increased by fifteen per cent with a suitable carbon addition. Also an improved induration cycle offered the possibility of a significant energy reduction within the process with no adverse effect on pellet quality. A...

Sommaire: Kidd Creek Mines primarily employs sublevel blasthole sloping for underground mining operations. During pillar recovery in No. 1 Mine and panel mining in No. 2 Mine, the free standing fill exposures may reach a height of 100 m or more. Consequently, a competent consolidated rockfill has been required to fill the mined openings.
Since 1976, a total of more than fifty slopes and pillars have been filled with over four million tonnes of backfill. Fill exposures, up to heights of 100 m, have...
