• Coal Mine Methane: A Review of Capture and Utilization Practices with Benefits to Mining Safety and to Greenhouse Gas Reduction
  5/1/2011 - Peer reviewed journal articles
  This 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.
• Stochastic Modeling of Gob Gas Venthole Production Performances in Active and Completed Longwall Panels of Coal Mines
  11/1/2010 - Peer reviewed journal articles
  This paper describes a practical approach for implementing stochastic determination of gob gas ventholes production performances and for generalizing the prediction capability of deterministic models.
• Determining Flame Travel Measurements from Experimental Coal Dust Explosions
  9/1/2010 - Conference papers
  NIOSH 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.
• Reservoir Diagnosis of Longwall Gobs Through Drawdown Tests and Decline Curve Analyses of Gob Gas Venthole Productions
  7/1/2010 - Peer reviewed journal articles
  During 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...
• Rapid Detection and Suppression of Mining Equipment Cab Fires
  4/1/2010 - Peer reviewed journal articles
  This 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.
• A Century of Bureau of Mines/NIOSH Explosives Research
  3/1/2010 - Conference papers
  The authors' goal is to summarize the totality of the USBM's explosives and blasting research.
• Development of Multiple Regression Functions for Performance Prediction of Gob Gas Ventholes for Sealed and Active Longwall Mines
  2/1/2010 - Conference papers
  A 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.
• Historical Development of Technologies for Controlling Methane in Underground Coal Mines
  1/1/2010 - Conference papers
  This paper discusses several milestone events that show the progress of methane control research in underground coal mines.
• How Does Limestone Rock Dust Prevent Coal Dust Explosions in Coal Mines?
  9/1/2009 - Peer reviewed journal articles
  This study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.
• Reservoir Rock Properties of Coal Measure Strata of the Lower Monongahela Group, Greene County (Southwestern Pennsylvania), from Methane Control and Production Perspectives
  3/1/2009 - Peer reviewed journal articles
  This 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.
