• An Analysis of Roof Bolter Fatalities and Injuries in U.S. Mining
  8/1/2017 - Peer reviewed journal articles
  This paper analyzes U.S. roof bolter fatal and nonfatal lost-time injury data at underground work locations for all commodities from 2004 through 2013 and determines risk indices for six roof bolting tasks.

• Evaluations of Bit Sleeve and Twisted-Body Bit Designs for Controlling Roof Bolter Dust
  2/1/2015 - Peer reviewed journal articles
  A paper detailing the use of a bit sleeve in combination with a dusthog-type bit to improve dust extraction during the critical initial phase of drilling.
• Directional Control-Response Compatibility Relationships Assessed by Physical Simulation of an Underground Bolting Machine
  3/1/2014 - Peer reviewed journal articles
  A study conducted to examine the pattern of direction errors made during the manipulation of a physical simulation of an underground coal mine bolting machine to assess directional control-response compatibility relationships.
• Visual feedback system to reduce errors while operating roof bolting machines
  2/1/2013 - Peer reviewed journal articles
  An experiment was conducted to explore coding and directional compatibility on roof bolting equipment and to determine the feasibility of a visual feedback system to alert operators of critical movements and workers in close proximity to the equipment.
• Development of a canopy air curtain to reduce roof bolters' dust exposure
  7/1/2012 - Peer reviewed journal articles
  This experimentally designed air curtain, adapted for roof bolting machines used in this study, is based upon previous design prototypes, computational fluid dynamics (CFD) simulations and trial-and-error testing.
• Respirable Quartz Hazard Associated with Coal Mine Roof Bolter Dust
  6/1/2010 - Conference papers
  This study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
• Less Sound Underground: Reducing Roof Bolting Machine Drilling Noise
  4/1/2010 - Conference papers
