Shotcrete Design and Installation Compliance Testing: Early Strength, Load Capacity,Toughness, Adhesion Strength, and Applied Quality4/1/2015 - Reports of InvestigationsA report on a research study to document and develop safe practices for the use of shotcrete as ground support in underground mines, particularly in underground metal mines operating in weak host rock.
3/1/2014 - Peer reviewed journal articlesAn article examining the large body of noninjury roof fall reports in order to gain insight into the characteristics of roof falls in coal mines.
9/28/2012 - News articlesNIOSH's OMSHR is starting a new project to produce guidance and tools to improve management of rib fall hazards.

1/1/2012 - Peer reviewed journal articlesA comprehensive analysis of these events was conducted to better understand where and why these incidents occurred.
6/1/2011 - Technology NewsTo develop a practical method of measuring shotcrete adhesion strength in underground mines.
1/1/2011 - Peer reviewed journal articlesIn 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.
2/1/2010 - Conference papersNIOSH is investigating the use of shotcrete in weak rock mass mines with the objective of reducing fatalities and injuries resulting from rock fall accidents.
1/1/2010 - Peer reviewed journal articlesAn understanding of the geologic and stress conditions which lead to roof falls is necessary to assess the risk of failure and to design roof reinforcement to improve stability.
1/1/2010 - Conference papersThis paper describes the impact of ground control research by the Bureau of Mines and NIOSH on the safety of underground coal miners.
