Sommaire: The Province of Manitoba tabled a Budget on March 11, 1992, which contains some important new initiatives designed to improve the fiscal environment for mining in the province. In addition, the Minister of Energy and Mines has released details of the Mineral Exploration Incentive Program which was originally announced in the 1991 Budget.

Sommaire: This paper addresses the occurrence and indicated causes of conveyor fires in North American and European underground mines. Some significant conveyor fires which have been experienced in recent years in Canadian hardrock mines are then reviewed. The nature of existing conveyor monitoring technology is considered in the context of such fire hazards. Experiences with new monitoring technology recently installed at several conveyor sites at Inco Ltd. mines are then reviewed.

Sommaire: Conveyor belts installed in an underground mine can be a potential source of a major fire, thus the need for fire-retardant belting. A Canadian Standard, CAN/CSA-M422-M87, incorporating a small-scale flame test, a drum-friction test, a flame propagation test and an electrical surface-resistance test, has been developed to meet the varied needs of the mining industry. It is recommended that mines use Types A and B belting described in that Standard, because they will have passed the large-scal...

Sommaire: The Quebec Mining Association has for many years been supportive of the activities of the Centre de recherches mmerales which were initiated to ensure regular production hoist and cable inspections to maintain safety and productivity standards in underground mines in Quebec. CRMand CANMET have agreed to fund a Quebec Mineral Development Agreement contract to capture this accumulated knowledge.
Using VP-EXPERT to process the information and subdirectories to store regulations, the prototype...

Sommaire: Midwest Joint Venture (MJV) owns a high-grade uranium deposit in northern Saskatchewan. The deposit is located too deep below surface to be mined economically by open pit methods, and as a consequence, present plans are that it will be mined by underground methods. High-grade uranium ore of the type at MJV, encased in weak, highly altered ground and with radon-rich water inflows, has not before been mined by underground methods.
The test mining phase of the project, completed in 1989, had...

Sommaire: The use of hydraulically delivered classified tailings sands to provide ground support in large mining operations is still widespread despite recent developments of alternate backfilling methods and materials. The major disadvantages of the use of hydraulic fill are the costs and risks associated with slurry delivery. The main risk is that of bulkhead failure resulting from sand liquefaction due to insufficient operational control or due to dynamic loading from earthquake or rockburst. That...

Sommaire: Graphite is one of the most versatile of non-metallic minerals because of its diversified properties, for example: it is unctuous; it marks readily; burns slowly; is almost chemically inert; is flexible over a large temperature range; is a good conductor of heat and electricity; is hydrophobic; has a negative temperature coefficient of resistivity; has excellent weathering properties; tends to emulsify with water-in-oil; is readily soluble in iron; and after oxidative treatment, can exfoliate...

Sommaire: This paper describes recent developments at Inco Limited, Ontario Division, in the field of information systems for automated mining. A CA TV cable network has been combined with a broad spectrum radio antenna system to allow the supply of voice, data and video services to underground mining. The system formed the basis of a field experiment at the Copper Cliff North Mine of the Ontario Division in 1990.
The experimental information system was developed to supply underground mining with...
