Evidence that Reducing Knee Injuries in Underground Mining may have a Substantial Impact on Mine Company Finances12/1/2010 - Peer reviewed journal articlesTo encourage mining companies to implement knee injury training programs and interventions, NIOSH performed an analysis of workers’ compensation data for one underground coal mine in Illinois and six in Pennsylvania.
9/1/2010 - Peer reviewed journal articlesSonic travel time logging of exploration boreholes is routinely used in Australia to obtain estimates of coal mine roof rock strength. This paper describes research aimed at developing a correlation for use in the U.S.
5/1/2010 - Peer reviewed journal articlesNIOSH studied methods to prevent workers from being entangled in machinery at mining operations. A description of intelligent video, the technology, test procedures and results, implementation challenges, and future research needs are discussed.
Characteristics of the Top Five Most Frequent Injuries in United States Mining Operations, 2003-20071/1/2010 - Peer reviewed journal articlesThis report describes an alternative method of analyzing and presenting MSHA data for the purpose of identifying high-cost, high-severity injuries and illnesses.
Elastic and Shear Moduli of Coal Measure Rocks Derived from Basic Well Logs Using Fractal Statistics and Radial Basis Functions12/1/2009 - Peer reviewed journal articlesA new approach was tested and it was demonstrated that it could be used for prediction of elastic and shear moduli of coal-measure rocks with reasonable accuracy.
Improvements in Seismic Event Locations in a Deep Western U.S. Coal Mine Using Tomographic Velocity Models and an Evolutionary Search Algorithm9/1/2009 - Peer reviewed journal articlesMethods of improving seismic event locations were investigated as part of a research study aimed at reducing ground control safety hazards. Results obtained using different velocity models are compared.
A Hydrodynamics-Based Approach for Predicting the Blast Damage Zone in Drifting as Demonstrated Using Concrete Block Data8/1/2009 - Peer reviewed journal articlesThis paper presents a blast design technique based on a hydrodynamic method and introduces modifications to account for different explosives from those used in a calibration test.
8/1/2009 - Peer reviewed journal articlesNIOSH conducted a statistical study of available data regarding frictional ignitions in the United States from 1983 to 2005 to determine and define conditions controlling their occurrence.
7/1/2009 - Technology NewsNIOSH has been performing research to analyze and reduce hazardous noise exposure in mines.
5/1/2009 - NIOSH/USBM numbered publicationsThis manual describes the Determination of Sound Exposures (DOSES) software developed by NIOSH for use by mine management and safety personnel to simplify record keeping and analysis associated with time-motion studies and worker noise exposures.
