2/1/2002 - Conference papersThis paper examines methods for limiting occupational silica exposures for roof bolting personnel in underground coal mining. It also evaluates a metal rake, a flexible insert, and a rigid insert for cleaning the roof bolter dust collector box.
-
2/1/2002 - Conference papersThis report discusses a cooperative research study performed on a surface drill retrofitted with a new pressurization and filtration system. Respirable dust concentrations were substantially reduced from 0.64 mg/m3 during pre-testing to 0.05 mg/m3 duri...

Laboratory Evaluation of a Canopy Air Curtain for Controlling Occupational Exposures of Roof Bolters6/1/2001 - Conference papersTesting at NIOSH assessed the effectiveness of a canopy air curtain for controlling occupational exposures to respirable silica and coal dusts.
-
2/1/2001 - Book chaptersA study of dust control technology and practices to reduce the occurrence of lung diseases in miners.
-
4/1/2000 - Peer reviewed journal articlesA recent report evaluating silica exposure levels in the metal/nonmetal mining industry noted that bag packaging and loading are some of the occupations at the greatest risk.
