• Use of Occupational Ethnography and Social Marketing Strategies to Develop a Safety Awareness Campaign for Coal Miners
  12/1/2008 - Peer reviewed journal articles
  This article describes how occupational ethnographic techniques provided insights needed for "new product development."
• Possible Impact of New Safety Technology Developments on the Future of the United States Mining Industry
  11/1/2008 - Conference papers
  This paper discusses the changes that new legislation and regulations are making to the industry and current research that is producing technologies to make mining safer and will likely impact the future of mining in the U.S.
• NIOSH Research for Monitoring and Controlling Methane at U.S. Underground Coal Mining Operations
  11/1/2008 - Conference papers
  This work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
• Coal Bed Discontinuity Effects on the Production of Degasification Boreholes and on Emissions During Longwall Mining
  10/1/2008 - Conference papers
  This 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...
• Reinforcing Coal Mine Roof with Polyurethane Injection: 4 Case Studies
  10/1/2008 - Peer reviewed journal articles
  This paper gives the results of 4 case studies concerning the interaction between polyurethane (PUR) and coal mine roof in order to determine the mechanism of reinforcement, in both highly fractured rock and unfractured rock.
• Application of Phased Array Technology for Identification of Low Frequency Noise Sources
  10/1/2008 - Conference papers
  This paper describes research to control dominant noise sources in continuous miners. This work ranks noise radiated by different conveyor sections and determines the effect of a urethane-coated tail roller on the noise radiated by the tail section.
• Coal Mine Burst Prevention Controls
  7/1/2008 - Conference papers
  This paper reviews 11 prevention control techniques for coal mine bursts.
• Advances in Grid-Based Numerical Modeling Techniques for Improving Gas Management in Coal Mines
  6/1/2008 - Conference papers
  This 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...
• Rock Mass Behavior and Support Response in a Longwall Panel Pre-Driven Recovery Room
  3/1/2008 - Conference papers
  Some surprising results were revealed in this study designed and implemented by NIOSH to evaluate the effectiveness of pre-driven longwall recovery rooms supported with pumpable concrete roof supports.
• Reservoir Modeling-Based Prediction and Optimization of Ventilation Requirements During Development Mining in Underground Coal Mines
  2/1/2008 - Conference papers
  This 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...
