6/1/2010 - Conference papersThis paper presents a mathematical model based on the conservation of mass principle describing the flow of air (nitrogen and oxygen), methane, and carbon dioxide into and out of a sealed atmosphere and time-dependent changes in gas concentration.
-
6/1/2010 - Conference papersIn this NIOSH study, a computational fluid dynamics (CFD) model developed in previous work is used to model the effect of seal leakage on spontaneous heating of coal in longwall gob behind the seal.
-
11/1/2009 - Conference papersThis paper seeks to encourage scientific discussion among international peers since preventing explosions within sealed areas is of interest to underground coal operators and regulators.
-
10/1/2009 - Conference papersThis report describes a new seal testing program that will provide essential validation data for mine seal analysis and design methods.
-
2/1/2009 - Conference papersThis paper describes the effort to create a reliable in-mine mobile plant for extracting nitrogen gas from the mine atmosphere. The gas produced by this novel technology can be used to create an inert environment in sealed mine areas.
-
2/1/2010 - Conference papersThis paper presents an overview of a novel PSA (pressure swing adsorption) plant, the details of the gas injection tests and CFD modeling work.
-
10/1/2009 - Conference papersThe objective of this research is to estimate the cementitious seal/rock interface properties from full scale test results.
-
2/1/2009 - Conference papersNIOSH has initiated a seals research program with collaborators from Safety in Mines Testing and Research Station (SIMTARS) in Australia, West Virginia University (WVU), the Naval Research Laboratory (NRL), and U.S. Army Corps of Engineers (USACE).
-
11/1/2007 - Conference papersThis paper presents a summary of remote mine firefighting technologies used in U.S. underground coal mines and the results of completed NIOSH research in that area.
-
6/1/2006 - Conference papersNIOSH is conducting full-scale underground experiments at its Lake Lynn Experimental Mine to identify and remedy existing shortcomings of remote sealing technology in order to develop new and improved technologies for the mining industry.
