Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 20048/1/2006 - Reports of InvestigationsThis study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
Prediction of Longwall Methane Emissions and the Associated Consequences of Increasing Longwall Face Lengths: A Case Study in the Pittsburgh Coalbed6/1/2006 - Conference papersNIOSH conducted a study with the goal of characterizing methane emissions from increasing face lengths in the Pittsburgh Coalbed and providing a method of predicting emissions increases from longer faces and of planning for more methane control.
6/1/2006 - Conference papersNIOSH conducted a longwall methane emission and mining time study at a Pittsburgh Coalbed mine to predict emissions from a longer face, and developed and applied mathematical formulas and constants to characterize four emission contributors.
1/1/2006 - Conference papersToxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In this study, 10 lb. charges of confined blasting agent were detonated in a closed chamber, and then detonation gases were analyzed.
2/1/2005 - Conference papersDescribes a small-scale field study to identify key factors that may contribute to the migration of CO through the ground.
5/1/2000 - Peer reviewed journal articlesOptical technologies have progressed rapidly in the past 15 years. NIOSH is conducting a study to help provide a scientific basis for developing appropriate safety guidelines for optical equipment in underground coal mines.
3/1/1999 - Conference papersEmerging laser technologies are quickly gaining acceptance in the industrial workplace. This NIOSH research provides a scientific basis for developing safety guidelines for optical equipment in the presence of flammable methane gas and coal dust.
1/1/1994 - Information CircularsThis paper describes the history and technology of methane drainage in the US and other countries.
1/1/1992 - Reports of InvestigationsReports on the U.S. Bureau of Mines development and testing of an instrinsically safe methane monitor based on differential absorption of infrared light.
4/2/2020 - Research projectsA project to develop and implement workplace solutions to reduce miners’ overexposure to hazardous airborne contaminants emitted from diesel-powered equipment.
