2/1/2010 - Conference papersA discussion of the NIOSH-developed software suite for methane control and prediction (MCP) based on an artificial neural network (ANN) is presented in this paper.
-
1/1/2010 - Conference papersThis paper discusses several milestone events that show the progress of methane control research in underground coal mines.
-
11/1/2008 - Conference papersThis work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
-
10/1/2008 - Conference papersThis study presents a numerical investigation of geological discontinues in the coalbed using reservoir simulations of the effects of partings and permeability facies and lithotype changes on the production performances of vertical and horizontal degasi...
-
6/1/2008 - Conference papersThis paper summarizes the modeling efforts conducted by NIOSH in the U.S. and CSIRO in Australia to address various gas management issues encountered in longwall mines using the application of computational fluid dynamics (CFD) and numerical reservoir m...
-
6/1/2008 - Conference papersThis study proposes a principle component analysis (PCA) and artificial neural network (ANN) approach to predict the ventilation methane emission rates of U.S. longwall mines and the optimum combination of degasification boreholes based on the given cha...

11/1/2007 - Peer reviewed journal articlesA discussion the spatio-temporal volumetric strains in a consolidated Pittsburgh seam coal sample which were evaluated while both confining pressure and carbon dioxide CO2 pore pressure were evaluated.
-
9/1/2007 - Conference papersThis paper discusses methods for protecting U.S. underground coal mines from explosions of methane gas and coal dust, and presents new research, such as the Coal Dust Explosibility Meter, a handheld device to directly measure coal dust explosibility.
-
7/1/2007 - Peer reviewed journal articlesThis paper presents the development and results of a comprehensive, "dynamic," three-dimensional reservoir model of a typical multi-panel Pittsburgh coalbed longwall mine. Results presented in this paper include a simulation of gas flow patterns from th...
