7/22/2014 - Contracts and cooperative agreementsA contract to develop a spray-applied polyurea coating system that would upgrade existing 20-psi approved mine seals to withstand blast pressures greater than 60 psi.
5/28/2014 - Contracts and cooperative agreementsA contract to transfer protective structure design technology from the defense establishment to the design and construction of seals in the coal industry.
7/1/2012 - Peer reviewed journal articlesThe research presented in this paper investigates the total leakage of a stopping, including air leakage through the stopping, at the stopping perimeter, and through the coalbed.
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.
1/1/2010 - Peer reviewed journal articlesThis paper discusses some concepts and preliminary test results for a Passive Mine Blast Attenuator (PMBA) that can provide a useful alternative to increasingly larger and stronger stand-alone mine seals.
10/1/2009 - Conference papersThe objective of this research is to estimate the cementitious seal/rock interface properties from full scale test results.
