Sommaire: A computer model has been developed which is capable of evaluating alternative production schedules (long- and short-range) of an open pit mine once the ultimate pit limits have been defined. The model user can choose the best alternative according to cashflow considerations and the particular mining conditions. The model involves a combination of simulation for long-range production scheduling and linear programming for short-range scheduling.

Sommaire: In mid-1986, a world-class mining enterprise was created in British Columbia, bringing together the copper mining operations of Lornex Mining Corporation and Cominco into a new entity, Highland Valley Copper. This paper will focus on the background and rationale for the formation of this partnership, the resulting operating changes and the productivity and cost benefits expected.

Sommaire: In October 1982, RioAlgom Limited, purchased a tin prospect near East Kemptville, Nova Scotia, from Shell Canada Resources. This purchase led to the development of the first substantial tin mine in North America. This paper deals with the drilling and blasting operations at Rio Algom, in particular the use of emulsion explosives technology. This presentation describes what emulsion explosives and Heavy AN/FO are, and the support system used to deliver these products to the blast site.

Sommaire: The Iron Ore Company of Canada (IOC) operations in Labrador and Quebec, in Canada, is among the largest open-pit mining complexes on a world wide basis. Since the 1981-82 recession, IOC has embarked on a comprehensive cost reduction and productivity improvement program in order to survive in the world iron ore market.This paper will outline the approach used in prioritizing the cost reduction items.

Sommaire: Zinc-iron alloy coatings can be produced by either thermally alloying hot-dipped galvanized steel or by electrodeposition. Stelco Inc. produces a thermally alloyed Zn-Fe alloy-coated steel, which is mechanically wiped to remove free zinc.
A more extensive use of Zn-Fe alloy-coated steel has been predicted for unexposed autobody and structural part applications, since this material is characterized by good spot weldability and formability, and provides superior corrosion resistance under...

Sommaire: Exploration results over three overburden drilling anomalies defined by the Ontario Geological Survey in 1981 in the Kirkland Lake area, Ontario are presented. The anomalies come from lowland areas where overburden is thickest. By mapping the bedrock and surficial geology, by prospecting, humus sampling and shallow till sampling over the surrounding upland surfaces, one can initially evaluate such overburden drill anomalies without costly reverse circulation drilling. The drilling should...
