• 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.
• Analysis of Applied Forces and Electromyography of Back and Shoulders Muscles When Performing A Simulated Hand Scaling Task
  5/1/2010 - Peer reviewed journal articles
  This article describes experiments simulating rib scaling from an elevated bucket to examine force generation and electromyographic responses using two types of scaling bars at five target heights ranging from floor level to 176 cm.
• Pillar and Roof Span Design in Stone Mines
  1/1/2010 - Peer reviewed journal articles
  Underground stone mines in the United States use the room and pillar method of mining in relatively flat laying deposits. Roof and rib falls account for 15% of all lost time incidents. This paper presents the result of a study to improve pillar and roof...
