Mining Respiratory Training
respiratory protection for the coal mining industry this presentation is specific to the respiratory protection needs of the coal mining industry. many of the concepts outlined within are highly relevant to other industries, but have been placed into a coal mining context.highly explosive gas found in underground coal mines that is released from the coal as is being mined. device worn by a miner to filter dust out of the air in which they breath. ear protection. devices worn by miners that go over or in the cars to protect against hearing loss.At the beginning of this project there were no msha-approved systems available for use in underground coal mines. near the conclusion of this project, geosteering mining services of frederick mining controls obtained the first msha approval for use of the device on cms in underground coal mines. geosteering called the system tramguard.
