7/1/2010 - Conference papersIn this paper, the findings of a survey of roof span stability issues and design practices are presented, and the observed factors contributing to roof instability are discussed.
-
7/1/2010 - Conference papersThis paper makes use of numerical models to examine the interaction between typical pillar systems and the surrounding rock mass for weak and strong geological conditions at various spans and depths of cover.
-
5/1/2010 - Peer reviewed journal articlesCurrent research is addressing many machine safety issues in both underground and surface mining. This study identified some specific miner activities and machine types that may need further attention.
-
3/1/2010 - Peer reviewed journal articlesThis publication details the results of NIOSH studies to examine operating speeds based on usage and seam height.
-
3/1/2010 - Conference papersThe effect of inflow and outflow of gas on the potential spontaneous heating in the gob was investigated using the computational fluid dynamics (CFD) model.
-
2/1/2010 - Conference papersThis paper describes field tests conducted by NIOSH to evaluate the effectiveness of a wet head continuous mining machine for reducing dust exposure for continuous miner operators.
-
2/1/2010 - Conference papersThe goal of this study was to determine the potential saving in workers' compensation (WC) premiums that could be achieved due to a reduction in rock fall injuries after roof screening.
-
12/1/2009 - Information CircularsThis document describes principles of noise control to operators, safety personnel, and mechanics in the mining industry so that they can evaluate the extent of a noise problem, determine the best approach, and apply the most appropriate solution.
-
9/1/2009 - Peer reviewed journal articlesThis study evaluates the circumstances leading to fall from equipment injuries in the mining industry.
-
9/1/2009 - Peer reviewed journal articlesThis paper describes the performance of LED and INC sources in cap lamps in terms of correlated color temperature, color rendering, light output, electric power, ambient temperature and air flow, and light source aging.
