Sommaire: The last edition of lay. Notes expressed concern about two proposed tax changes in Finance Minister Paul Martin's 1995 budget that could have detrimental effects on Canada's mining industry. This month, Tax Notes expands on these concerns. This article is based on a paper that the author presented at CIM '95 in Halifax.

Sommaire: Friction winders and double drum winders have been used in the vertical shaft mining industry for over 100 years. In that time, there have been many changes made in the electronic and mechanical fields of hoisting, but few changes made in the manufacturing and performance of steel wire rope, until recently.
In the past ten years, with the advent of high polymer thermoplastics, the industry has seen some major advancements in steel wire rope. By incorporating a polymer with steel, improvement...

Sommaire: This paper reviews the evolution of Canadian surface and underground mining automation, principally relating to: advances in communications, initial development of machine teleoperation from line-of-sight remote control, and islands of automation. The eventual role of telerobotics and minewide robotic mining remains to be resolved. The progress and approaches adopted have tended to vary within each sector of the mining industry. Recent information technology advances have made possible the...

Sommaire: The most commonly used tendon supports in the Sudbury area include rock bolts, rebars, friction anchors and cable bolts. Due to the fact that these tendons are physically different and employ different anchoring systems they offer varying degrees of stiffness, yield ability, load capacity, anchor dependability and energy absorption. These differences coupled with variable rock mass and changing stress conditions have made it challenging to engineer the design of an effective support system....

Sommaire: In March 1993, Ram Raising Limited was faced with a challenge. Placer Dome Incorporated, Dome Mine Division, requested from Ram Raising that they design station excavation into the existing No. 8 shaft from No. 3 mine levels. This work had to be done without loss of production time in the underground department.
Due to the time frame of the project, every detail had to be carefully considered, with extra care that all pros and cons had been worked out.
Ram Raising submitted a work plan that...

Sommaire: Advances in our knowledge of the petrochemical attributes of deposit environments and of the character and extent ofhydrother-mal systems associated with certain deposit types has resulted in increased application of lithogeochemistry to exploration programs. Lithogeochemistry can be used to vector an exploration program toward an area of high potential through the use of a series of collapsing scales of analysis from a tectonic subprovince down to a particular stratigraphic segment. In the...
