Summary: A computer simulation model of a dragline has beer, developed for the study of alternative dragline deployment schemes for varying geological and mining conditions. In this paper, the mathematical aspects of the model, the input data and output results are discussed. An application of the model to a coal mine in eastern Kentucky is presented.

Summary: This paper provides a bird's eye view of the pattern of gold discoveries since 1823, the year of Canada's first gold find, up to 1983. Within this 160-year period, more gold was discovered in Canada during the last ten-year period (1973-1982) than during any previous decade. The record suggests that the potential for further major gold discoveries is high, which bodes well for the future of Canadian gold mining.

Summary: Draft income tax amendments aimed primarily at certain carve-out arrangements prevalent in the oil and gas industry could have devastating results for long standing royalty arrangements in the mining industry. Whether or not this potentially damaging effect is intended is largely beside the point—the point is that the mining industry would be we/I advised to become familiar with the draft amendments and make sure that the potential damage to existing and future royalty agreements is...

Summary: The Line Creek Mine of Crows Nest Resources started mining coal in the fall of 1981. There are seven mineable seams with thicknesses ranging from 1.5 to 13 metres and with dips varying from 0 degrees to 60 degrees. This, together with internal partings and the very friable nature of the coal, creates a number of mining problems.
The coal is divided into zones depending on the dip of the seam. Each zone requires a different mining technique to ensure optimum recovery and low dilution while...

Summary: The New Pascalis property is situated in Louvicourt and Pascalis townships, about 200 km east of Val d'Or, Quebec. It is made up of 38 claims under option to SOQUEM since A ugust 1, 1981 during which time SOQUEM has earned a 60% interest. The property is underlain by archean basaltic volcanics that have been intruded along the west boundary by the Bourlama-que batho/ith, and by north-trending dykes.
The 1982 discovery is related to the re-evaluation of a 1931-gold showing located in the...
