9/28/2012 - News articlesPreventing coal mine explosions requires a suite of control strategies and NIOSH continues to conduct research to develop more effective intervention measures.
-
9/17/2012 - Contracts and cooperative agreementsA contract to evaluate the use of Barricade II Fire Blocking Gel for use in mine fire prevention, control, or fire suppression technologies.
-
9/17/2012 - Contracts and cooperative agreementsA contract to integrate a micro electro mechanical system (MEMS) component into specialized electronics to measure methane levels in underground coal mines.

1/1/2012 - Peer reviewed journal articlesIn this study, computational fluid dynamics (CFD) modeling was conducted to optimize gas sampling locations for the early detection of spontaneous heating in longwall gob areas.
-
9/1/2011 - Peer reviewed journal articlesThis paper presents technical and application aspects of a new software suite, MCP (Methane Control and Prediction), developed for addressing some of the methane and methane control issues in longwall coal mines.
-
5/1/2011 - Peer reviewed journal articlesThis article reviews the technical aspects of coal mine methane (CMM) capture in and from coal mines, the factors affecting CMM accumulations in underground coal mines, methods for capturing methane using boreholes, and borehole designs.
-
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...
