Sommaire: A brief history of previous mining activity on Coal Mountain, near Corbin, British Columbia, is followed by a description of the steps leading up to the resumption of mining in 1974 by Byron Creek Collieries. New developments, including a preparation plant, a rail spur and a totally enclosed facility, as well as operating techniques, are also discussed.

Sommaire: The various elements of longwall mine design are reviewed, particularly as they apply to conditions in the coalfields of the Plains region of Alberta. The following recommendations are made: (1) optimum panel lengths of 1000 to 2000 metres; (2) face lengths of 100 to 150 metres; (3) the use of retreat methods; (4) the restriction of floor undulations to less than 15 degrees.

Sommaire: Coke is the most costly item in steelmak-ing via blast furnaces. Recent innovations in cokemaking have been directed toward reducing this cost while simultaneously improving coke quality and expanding the range of coals used in the process. It is also important to meet increasingly stringent environmental legislation.Improvements in coke quality have been achieved by novel blend selection procedures, by charge density control using both selective pulverization and partial briquetting, and by...

Sommaire: Gamma-ray spectral logging, a useful technique for uranium exploration and evaluation, has generally been underutilized by the Canadian mining industry. Provided that the technique is properly applied, it is capable of yielding reliable quantitative information regarding the distribution of uranium and other radioelements along the borehole under most conditions.In practice, there are numerous factors which potentially can degrade the quality of the log and thus any quantitative interpretatio...

Sommaire: Higher metal prices have resulted not only in increased exploration and production, but also increased activity in the purchase of mining properties and mines. This article discusses some of the basic income tax considerations to be taken into account on the disposal of an interest in a mining claim or an active mining operation. It notes the importance of an appropriate allocation of the purchase price amongst the various categories of assets, and discusses the tax implications to both...

Sommaire: Methods of extracting copper are evaluated in terms of innovations during the 1970's, and predictions to the end of this century are made. It is concluded that between one and two new smelters and refineries will be needed per year until the turn of the century, and that most of these smelters will be of the oxygen or oxygen-enriched flash furnace type. For converting, the Peirce-Smith converter will still predominate, but the Hoboken converter will play an increasingly important role. Five...

Sommaire: Simulation techniques may be used to optimize existing processes and plant operations, and in plant design at the engineering study stage of a project. This paper describes the latter application, using a computer, to optimize the concentrate stockpile requirements of a modern copper smelter.A large open-pit mining operation is envisaged and it is assumed that copper concentrate is smelted in two flash furnaces. The proposed mining plan gives rise to metallurgical considerations in smelting...

Sommaire: Western Canadian coking coals are located in the Rocky Mountains arid foothills of British Columbia and Alberta. They are typical of non-marine coals, characterized by total sulphur contents of less than one per cent and with ash contents of10-30 weight per cent. This mineral matter is composed principally of kaolinite and quartz.The petrographic compositions of most of the coking coals which constitute the 2.065 billion tonnes of British Columbia's measured reserves, and the compositions of...
