• Current trends in Reducing Ground Fall Accidents in US Coal Mines
  1/1/2011 - Peer reviewed journal articles
  In recent years, the number of some annual ground fall fatalities has approached zero, indicating that significant progress has been made. However, more progress is needed to reduce injuries caused by rock falling between supports and by rib falls.
• Current Trends in Reducing Ground Fall Accidents in US Coal Mines
  2/1/2009 - Conference papers
  Each of the electronic versions of the MSHA fatality reports since 1995 was analyzed in detail, categorized by the type of the ground fall hazard. The remainder of the paper is devoted to evaluating each of the five largest categories.
• Dynamic Failure in Deep Coal: Recent Trends and a Path Forward
  7/1/2008 - Conference papers
