| Abstract | Coals of all ranks from the age of Devonian to Miocene occur in different parts of Canada under diverse geologic and geotechnical conditions. From the geotechnical point of view the Canadian coalfields
can be divided into the following broad groups: Mountains, Foothills, Plains, Lignite region, Maritimes and the other minor areas across Canada. The prinicpal factors affecting geotechnical characteristics are: rock properties, tectonics, ground
stress, ground water, stratigraphy and lithology, dip, depth and coal rank. Both the Mountains and the Plains are geotechnicaliy problem areas, the former due to tectonics and the latter due to rock properties. Foothills have some better rating in
this respect. Saskatchewan Lignite region has some problems due to unconsolidated rocks in surface mining. Maritimes have favourable tectonics but have depositional and lithologic problems. These characteristic are discussed in this paper. |
