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

Component of jackleg drill helps position and stabilize drill, and support it's weight.

Technique

Operated by one person, the handle is furnished with a twist grip that allows the miner to control the speed of drilling. It has two hoses: one for compressed air to operate the drill, and one for water supply to cool and clean the drill. The hoses are looped together during transport to the drilling shaft to prevent any impurities from getting inside the drill. Compressed air is also supplied to the leg, which adds extra power to drilling; the miner only controls the stability and the angle of drilling and does not have to push on the drill. Compressed air at 100 psi. Joy Company History: http://www.joyglobal.com/Joy/About-Us/History.htm
