7/1/2000 - Peer reviewed journal articlesBecause of the need to provide short-term or real-time estimates of worker respirable dust exposure, porous foam may be a viable classification media for a low flow rate, disposable respirable dust sampler for use in the coal mining industry.
5/1/2000 - Peer reviewed journal articlesAn experimental program was conducted to evaluate the accuracy of some current methods for predicting the flammability of gas mixtures containing hydrogen and flammable or nonflammable volatile organic compounds (VOCs) in air.
5/1/2000 - Peer reviewed journal articlesThis paper reports the results of flammability studies for methane, propane, hydrogen, and deuterium gases in air conducted by the Pittsburgh Research Laboratory.
4/1/1999 - Peer reviewed journal articlesAn evaluation of strategies for monitoring methane levels during roof bolting in an extended cut entry.
2/1/1998 - Peer reviewed journal articlesCoalbed gas content measurements are commonly used in mine safety as well as coalbed methane resource assessment and recovery applications. Gas content determination techniques generally fall into two categories: (1) direct methods which actually measu...
