Abstract Le Québec recèle de nombreuses occurrences des éléments du groupe du platine (ÉGP). La grande majorité des occurrences sont associées à des minéralisations sulfurées de Cu-Ni. La conférence portera sur la distribution des ÉGP au Québec, en particulier dans la ceinture de Cap Smith, la Fosse du Labrador, la Baie James, l’Abitibi et le Grenville. Le contexte géologique et la composition des minéralisations seront abordés, afin de dégager une perspective sur le potentiel des ÉGP au Québec.

Summary: This paper reports on the development of a new methodology for automatic construction of discontinuity trace maps, in underground mine environments, using digital face mapping. A case study is presented where the performance of the developed automatic image analysis procedures are evaluated with reference to results obtained from scanline mapping. The practical implications of this work lie in the development of quick, more efficient and safer techniques to rock mass characterisation.

Summary: One challenge in applying information technologies in Mining is building a business case. In Mine Maintenance, there is a complex flow of information that contributes to making informed business decisions. By understanding those information relationships and the cost of wrong decisions, analysts can estimate the value of information flow. Developers can then ensure that systems deliver accurate information in a timely way. In this paper, general maintenance decision-making is discussed, with...

Summary: This paper will consider mineral processing in zero gravity dry environments typical of asteroids or comets. Pneumatic flow systems along with electrostatic or magnetic separation techniques will be explored. Pneumatic delivery of solids is used because of extreme temperature changes and the possible scarcity of water. Present earth-based processes and how they can be modified for these conditions will be examined.

Summary: Larger haul trucks are being used at surface mines in Canada thus requiring better haul roads to carry heavier loads. Haul road design is often based on past experience without sound engineering design. This can lead to under design resulting in costly road repairs, productivity losses, and increased truck maintenance costs.

A review of various road design methods showed that a method based on the resilient modulus of the construction materials combined with a critical vertical strain...

Exploration success lead to the installation of a hoisting plant capable of extracting 4,500 tonnes of ore and 1,800 tonnes of waste per day from a depth of 2,210 metres. The introduction of a new rope selection factor, permitting a safety factor of 4.0, represented the breakthrough required for a cost-effective project. This paper describes the...

Summary: Arsenic is a common impurity in copper sulfide concentrates treated pyrometallurgically, which inevitably during the smelting-converting process reports in the final copper product affecting its properties, but also it is a very toxic occupational hazard.

It has been recovered principally as arsenic trioxide by roasting or leaching then...

Summary: A continual objective of mine operations is to reduce ground control costs without compromising the overall safety or performance of the installed ground support. Any change in the ground support regime must not result in a less secure or safe workplace. The due diligence required to implement a change in rockbolting practice is extensive, particularly when the new bolting system has not been used at any other mining operation. Factors such as yield, shear strength and embedment strength must...

Summary: North America is blessed with over 25% of the world’s coal reserves. As a result, coal has provided a low cost energy base for power and steam production . However, over 75% of our solid fuel electric generating capacity was installed between 1960 and 1985. Since that time, very little new solid fuel capacity has entered operation in North America. Fortunately for power plant equipment suppliers, markets for new fossil steam generation have grown in Asia, India, China and the Middle...
