Elemental Carbon Levels at a Potash Mine

Journal of Occupational and Environmental Hygiene, 1997
Abstract A survey of worker exposures in a potash mine and mill was undertaken to evaluate diesel exposures during the feasibility effort of an epidemiologic study. Nineteen occupations were sampled. Results were averaged into six underground groups and three surface groups. Elemental carbon exposures, a diesel surrogate measure, were similar among all

Exposure assessment in German potash mining

International Archives of Occupational and Environmental Health, 2007
Between 1995 and 2003 a longitudinal study on miners in two German potash mines was planned and performed by BAuA in collaboration with K+S and IGF. Aim was to correlate exposure data to the results of medical examination of the miners in the respective mines' workforce and to use the detailed exposure investigation as a tool for risk assessment by the

Time-dependent hydraulic fracturing in Potash mines

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Abstract This paper investigates by numerical methods the cause(s) of mine seismicity and mine floding occuring at several potash mines in Saskatchewan, Canada. To assit in the investigation, a finite-element model based on visoelelastic/ viscoplatic material behaviour has been utilized.

Decommissioning planning for Saskatchewan's potash mines

2009
Saskatchewan's potash producing companies are now in the process of developing decommissioning and reclamation (D&R) plans for potash mines which were in operation many years before these plans were required by provincial regulations. The major problem is to develop a plan for the extensive piles of potash tails now stored on the surface in tails ...

Some Considerations in the Productivity of Potash Mines

Proceedings of the Human Factors Society Annual Meeting, 1982
Potash is one of the principal resources in the province of Saskatchewan. Its mining and production involves the efforts of men and machinery. Increases in productivity to meet increases in demand can be brought about by understanding and improving the work, environment and operator related human factors.
