1/1/2011 - Peer reviewed journal articlesStudy results of the role of various ventilation rates in the spontaneous heating of coal in underground mines found that there is an optimum ventilation flow to produce the maximum rate of temperature rise at the critical ambient temperature.
1/1/2011 - Peer reviewed journal articlesA field-expedient test method and portable on site test equipment have been developed to measure shotcrete strength in the first six hours after application.
The Potential Impact of Light Emitting Diode Lighting on Reducing Mining Injuries During Operation and Maintenance of Lighting SystemsNIOSH research indicates that LEDs can enhance safety by improving a miner’s ability to see hazards and by reducing glare. This paper considers whether LEDs can also reduce miner exposure to hazards during maintenance and operation of LED lighting.
Many rock fall injuries can be prevented with roof screen, but many coal mines are reluctant to use it due to added cost. This study looked at potential savings in workers' compensation premiums due reduced rock fall injuries after roof screening.
This study examines stress transmitted to anatomic landmarks of the knee (patella, combined patella tendon, and tibial tubercle) while in static kneeling postures without kneepads and while wearing two kneepads commonly used in the mining industry.
6/1/2010 - Peer reviewed journal articlesThis paper provides a summary of work done in a study on fires and explosions in underground U.S. coal mines that were caused by flame cutting and welding operations to determine the root causes of these types of fires and explosions.
5/1/2010 - Peer reviewed journal articlesCurrent research is addressing many machine safety issues in both underground and surface mining. This study identified some specific miner activities and machine types that may need further attention.
3/1/2010 - Peer reviewed journal articlesIn this paper, Computational Fluid Dynamics modeling of the effect of longwall face advance on the spontaneous heating of coals in a two-panel gob area using a bleeder ventilation system is presented.
3/1/2010 - Peer reviewed journal articlesThis publication details the results of NIOSH studies to examine operating speeds based on usage and seam height.
2/1/2010 - Peer reviewed journal articlesThe results of this study provide more insight into potential advantages and disadvantages of using biodiesel fuels for controlling emissions of aerosols and gases. Using diesel oxidation catalysts to control biodiesel emissions was re-examined.
