3/1/2009 - Peer reviewed journal articlesThis study presents reservoir and elastic properties of coal measure rocks in the Lower Monongahela Group in Greene County, southwestern Pennsylvania, with results that can be used as data sources for reservoir studies related to methane control.
-
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...
-
9/1/2008 - Peer reviewed journal articlesThis study presents a reservoir modeling approach to investigate the relative effects of different coalbed parameters on the migration of methane into development entries, and shows that this technique can be applicable to different coalbeds.
-
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 paper describes research conducted to compare the performance, including response time and accuracy, of selected instruments using infrared and catalytic sensors.
-
6/1/2008 - Peer reviewed journal articlesThis article describes the Coal Dust Explosibility Meter (CDEM), a hand-held instrument developed by NIOSH, which uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture, which is now commercially available.
-
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...
-
2/1/2008 - Conference papersThis NIOSH study presents an approach for prediction of methane inflow rates using coalbed methane reservoir modeling which can be used to limit the methane concentrations occurring as a result of the influences of various coalbed and operational parame...
