11/1/2010 - Peer reviewed journal articlesThis paper describes a practical approach for implementing stochastic determination of gob gas ventholes production performances and for generalizing the prediction capability of deterministic models.
-
9/1/2010 - Conference papersNIOSH conducted large-scale explosion experiments at the Lake Lynn Experimental Mine to investigate the inerting effect of limestone rock dust. Flame travel was measured using a conventional test and results were compared to a newer method.
-
7/1/2010 - Peer reviewed journal articlesDuring longwall mining, fracturing and relaxation in the gob creates new and highly permeable flow paths. The production rate-pressure behavior of a gob gas venthole (GGV) drilled over a longwall panel was analyzed by using multi-rate drawdown and decl...
-
4/1/2010 - Peer reviewed journal articlesThis paper discusses large-scale experiments conducted by NIOSH to evaluate the effectiveness of optical flame detectors, photoelectric smoke detectors, and combined ionization/photoelectric smoke detectors for detecting mining equipment cab fires.
-
3/1/2010 - Conference papersThe authors' goal is to summarize the totality of the USBM's explosives and blasting research.
-
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.
-
9/1/2009 - Peer reviewed journal articlesThis study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.
-
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.
