Maceral Affinity of Phosphorus in Coals from the Elk Valley Coalfield, British Columbia

British Columbia exports about 25 million tonnes per year of metallurgical coal from two coalfields, which follow the Rocky Mountains along the eastern edge of the Province. In the north there are two mines in the Peace River coal&Id and in the south, five mines in the east Kootenay coalfields (Figure I). The east Kootenay coalfields are divided into the Elk Valley, Crowsnest and Flathead field...

Numerical modeling of mining subsidence in the Southern Coalfield of New South Wales, Australia

Mining subsidence associated with longwall extractions beneath significant natural features such as rivers and streams in the Southern Coalfield of New South Wales has posed risks to the natural environment. In this paper, a case study is presented showing the methodology in two-dimensional UDEC (Itasca 2006) modeling for mining induced subsidence around river valley, taking advantage of the di...

Geology and Potential Coal and Coalbed Methane Resource of the Tuya River Coal Basin

This article forms pan of an ongoing study of the coal and coalbed methane resource potential of northwestern British Columbia. Other areas under study include the Bower basin coalfield, Telkwa coalfield and Tertiary coalfields of the Bulkley Valley. Tertiary sediments survive in many major watersheds in British Columbia. The sediments are generally not well consolidated, poorly exposed and the...

Context dependence of elk (Cervus elaphus) vigilance and wolf (Canis lupus) predation risk

To assess the relationship between predation risk perceived by elk (Cervus elaphus L., 1758) as evidenced by vigilance, we conducted focal animal observations in elk winter range.We stratified our observations in Glacier National Park, Montana, USA, andWaterton Lakes National Park, Alberta, Canada, in valleys with three wolf (Canis lupus L., 1758) population levels (Saint Mary Valley: no wolf; ...
