3/27/2014 - Reports of InvestigationsThis Report of Investigations details the results of a NIOSH investigation of temperature rise in mobile refuge alternatives.
7/1/2010 - Conference papersThe paper provides a basic set of input data and a modeling approach that can be used for numerical modeling investigations of various coal mine designs using the FLAC3D software package.
3/1/2010 - Peer reviewed journal articlesIn this paper, Computational Fluid Dynamics modeling of the effect of longwall face advance on the spontaneous heating of coals in a two-panel gob area using a bleeder ventilation system is presented.
7/1/2009 - Peer reviewed journal articlesThis paper discusses a study in which a three-dimensional CFD modeling of spontaneous heating of coal, based on the U.S. Bureau of Mines (USBM) large-scale coal chamber tests, was conducted.
3/1/2009 - Peer reviewed journal articlesThis study describes the development of an expert classification system used as a decision tool which can be used for degasification system selection using site- and mine-specific conditions.
