10/1/2009 - Peer reviewed journal articlesInstruments remaining in a test section of a lead/zinc/copper room and pillar mine where pillar mining had taken place 14 years before were read to monitor long-term stability and quantify time dependent behavior in the mine roof and backfill.
Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine AirThis paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
Fall From Equipment Injuries in U.S. Mining: Identification of Specific Research Areas for Future InvestigationThis study evaluates the circumstances leading to fall from equipment injuries in the mining industry.
External L5-S1 Joint Moments When Lifting Wire Mesh Screen Used to Prevent Rock Falls in Underground MinesThis study uses biomechanical modeling to estimate external moments about L5-S1 for sixteen lifting tasks, using two sizes of wire mesh screens, and presents recommendations to reduce spine loading.
Forecasting Gob Gas Venthole Production Performances Using Intelligent Computing Methods for Optimum Methane Control in Longwall Coal MinesIn this paper, the total gas flow rates and methane percentages from 10 GGVs were analyzed. The results showed that the two-hidden layer model predicted total production and the methane content of the GGVs with more than 90% accuracy.
This paper describes the performance of LED and INC sources in cap lamps in terms of correlated color temperature, color rendering, light output, electric power, ambient temperature and air flow, and light source aging.
Continuous Mining: A Pilot Study of the Role of Visual Attention Locations and Work Position in Underground Coal Mines8/1/2009 - Peer reviewed journal articlesThe purpose of this study was to perfect a method of gathering information on work positions and Visual Attention Locations needed by operators during the cutting phase and while the continuous miner trams to a new location.
7/1/2009 - Peer reviewed journal articlesThis paper discusses a study in which a three-dimensional CFD modeling of spontaneous heating of coal, based on the U.S. Bureau of Mines (USBM) large-scale coal chamber tests, was conducted.
6/1/2009 - Peer reviewed journal articlesThis paper discusses NIOSH mine illumination research to determine if light-emitting diode (LED) cap lamps can improve safety by reducing glare.
3/1/2009 - Peer reviewed journal articlesThis article is a review of recent accidents involving explosives transport both in the United States and outside of the United States.
