The equipment offered to the Museum comes from an experimental mine, establish by NRCan-CANMET to conduct testing and design improvements to mining equipment on the federal level. The CANMET-MMSL EXPERIMENTAL MINE in Val-d'Or, Quebec, was established in 1991 in response to Canadian and local mining industry needs for an increased emphasis on applied research. The former Beacon Gold Mine is an underground facility for in-situ testing and research in a true mining environment. The Experimental Mine is also available for individual companies to test equipment or for training purposes on a contract basis. CANMET-MMSL scientists at the Experimental Mine also offer a range of services to the local mining industry. The equipment suggested for acquisition represents the testing done by CANMET scientists. The mine comprises a unique underground hard rock testing site with an access ramp and five underground levels. There are two interconnected gold mines at this site. The earlier mine, Le Roy was opened from 1931-1932. It was operated by Le Roy Gold Mines Ltd. The Beacon II was open in mid-1980s and was owned by Mines Aurizon Ltd. There are over 2500 metres of drifts, plus raises and secondary openings and shrinkage stopes. Val-d'Or area is very important to Canadian mining since gold was discovered there in 1923. Gold, copper, zinc and lead are still mined there today. Val-d'Or had been and home to many mining companies such as Bourlamaque, Siscoe, Sigma, Sullivan, Lamaque, Osisco and Northern Star Mining. The history of the town reflects the region's economic dependence on mining. [Ref. 1]

Fonction

Connects multiple mine lamp batteries to charger.

Technique

Used at E.M. in Val-d'Or. The lamps are placed on the rack after every use, and are only removed when the miner is going into the mine. Each miner and his/hers lamp are assigned a number. This is a double-checking system to ensure that everybody has returned safely. In 2010, the batteries would not charge fully anymore and the Canmet purchased a new set (lamps, batteries, a charger and a rack are sold as a set). [Ref. 1] Please see extensive History of Koehler in Acquisition Proposal [Ref. 1]
