TRANSFER OF TECHNOLOGY quicklime, slaked lime and lime powder. The production of cement lies at around 150,000 t/a, the quicklime production at around 60,000 t/a and the lot size of lime powder at around 470,000 t/a. Approximately 40 % of the finished products are transported from the plant to their destination per railway, the remaining 60 % are transported per truck. Alongside the occupational safety, Greymont attaches priority importance to environmental protection, which is also due to its proximity to Banff National Park. Therefore the emission of harmful greenhouse gas was reduced by 8 % during the last three years.
Banff National Park The Exshaw open pit mine offered an overwhelming view of the mountain panorama of the Rocky Mountains and the Banff National Park, which was included in the program after the inspection of the mine. Since 1984 the park has been declared world cultural heritage by UNESCO and a small area of 28 km was alreay put under protection in 1885. Later the area was expanded, and today it encompasses an area of 6,641 km² and contains numerous summits with a height of over 3,000 m and seas, including the famous lake Louise. The village Banff lies in the center of the park. The park is visited each year by over 3 million tourists and offers an abundance of natural attractions, like for example hot mineral springs, glaciers, extended forests, deep gorges and mountain meadows with a multifaceted flora and fauna. The Banff National Park was one of the many cultural highlights of the excursion. On the early evening, after an extensive stay at the Lake Louise and in Banff, as well as after numerous brakes at various viewpoints, the group started their way back to Calgary. The next day brought the farewell from Canada. The group returned to Germany on 3rd May, after 5,500 km of driving, partly under winterly and partly under summerly conditions, interesting visits to mines and impressive experiences of nature.

Conclusions of the Trip This year’s excursion abroad of the Institute for Mining of the TU Clausthal to Canada was a big success, due to the great involvement and the extensive preparations of the student body, particularly the students of the ‘Förderkreis Fachschaft Geowissenschaften und Rohstoffe’, who organized the trip mostly by themselves. The study visit to Canada will have lasting impressions on all participants and the information obtained in the mines provide a valuable contribution to the understanding of the mining activities and methods, also due to the dimensions of open pits and equipments. In order to keep the experiences vivid and to share them with interested parties, a detailed mission report is being prepared and will shortly be published.
