Sommaire: The use of approved fire-resistant hydraulic fluids in equipment operating underground was made mandatory in British Columbia by amendment to the Provincial Mines Regulation Act effective January 1, 1975. This paper covers the action taken to achieve this, in the largest underground metal mine in British Columbia. Some evaluation of costs and effects based on experience to date is included.

Sommaire: The history and analysis of a structurally complex open-pit rock slope displacement are described. The failure involved part of the only haulage access to a major ore zone. The ongoing movement was monitored using an electronic distance-measuring device and a continuous electronic system specifically designed for the problem. A major fault, infilled with a thick clay gouge, and intersected by other structural features, resulted in the transfer of weight to a rock mass acting as a buttress in...

Sommaire: A unique deposit of barite exists near Brookfield, Nova Scotia. The crystals are extremely fine and the whole deposit virtually free of heavy metals. The deposit size was not large enough for conventional uses, such as the production of barium carbonate and drilling mud. In an effort to obtain maximum utilization, a program was begun to determine if U.S.P.-grade pharmaceutical barium sulphate for X-ray diagnosis could be produced.Early work was sufficiently encouraging to institute a...

Sommaire: Detailed studies have been conducted on the dispersion of uranium in stream waters and sediments around various types of mineralization and hitherto unexplained anomalous areas in the Okanagan Valley and Highland region of south-central British Columbia. These studies were part of the jointly funded and planned Federal-Provincial Uranium Reconnaissance Program of the Geological Survey of Canada and the British Columbia Ministry of Energy, Mines and Petroleum Resources. Statistical analysis of...

Sommaire: The low cost and availability of micro-computers and their peripherals provides the metallurgical engineer with the opportunity to use such computers in a wide variety of applications. In this paper, the authors describe the development of a low-cost data acquisition system capable of measuring up to 8 analogue channels at a sampling rate of up to 5000 measurements per second. This system is equipped with proper hardware and software so that the micro-computer can be linked to a central...

Sommaire: margin of the late Triassic Guichon Creek batholith in south-central British Columbia. Host to the ore are sedimentary and volcanic rocks of the western calc-alkaline belt of the Upper Triassic Nicola Group. In the mine area, the Nicola Group rocks are a stratigraphically complex sequence, at least 1800 feet thick, which have been subdivided into Basalt, Rhyolite, Carbonate and Clastic Sediment units. All the units strike and dip parallel to the margin of the Guichon Creek batholith and are...
