Summary: Mine hoist brakes must meet the following statutory performance criteria:

There should be two independent braking systems; at least one should act directly on the hoist drum.
If one brake fails, the others should be able to retard and stop the hoist safely before the descending conveyance, carrying the rated load, reaches any obstruction.
When all brakes apply,  decelerations should not be so violent that men travelling in the conveyance are injured.
The brakes shall...

Summary: An analysis of the number of industrial injuries shows that the mining sector is particularly affected, since mining is one of the most dangerous industrial activities in Canada. This has led to numerous inquiries, and supports the need for an in-depth study aiming at the identification of factors responsible for these accidents. One possible factor often pointed at is the small crews incentives and this paper presents a scientific approach applied to check a potential link between bonus and...

Summary: Radon emanation rates, J, and compositions of materials from the Canadian Certified Reference Materials Project (CCRMP) indicate that the fraction of the Rn produced that escapes, E, is usually 1% to 8% and the 23SU decay chain is nearly in secular equilibrium. For some Chinese ore standards, E values are higher than for the CCRMP materials. Standard ore tailings have 21°Pb concentrations higher than expected from their 226Ra concentrations and Rn escape rates (12 - 34%). Biological...

Summary: At the Falconbridge Limited, Canadian Nickel Division, Sudbury Operations, we investigated the "NO NOISE" ear muffs model NN3-F which is a Swedish product with foam-filled sealing rings (the Hellberg Standard Volume Hearing Protector). It is used extensively at Falconbridge mines in Sudbury.
The research which was carried out in the four Falconbridge mines was conducted under three different headings: manufacturer's attenuation data (psychophysical method), clamping force and head...
