7/1/2015An article presenting an assessment of the effects that ground control mesh might have on rock and float coal dust distribution in a coal mine.
-
4/1/2015 - 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.
-
3/4/2014 - Contracts and cooperative agreementsA contract to evaluate the role of gas desorbing on the failure of coal and the resultant influence on dynamic failures such as bumps, bursts, and outbursts.
-
8/20/2013 - PC softwareThis installable toolbar provides quick access to seven NIOSH ground control software packages.
-
6/1/2011 - Technology NewsTo develop a portable field-use testing system for conducting ASTM-1550-05 round determinate panel tests.
-
6/1/2011 - Technology NewsTo develop a practical method of measuring shotcrete early strength onsite in the first six hours after application using a partial beam test standard, ASTM C 1 16-90.

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.
-
5/1/2010 - Peer reviewed journal articlesThis 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.
-
2/1/2009 - Conference papersEach 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.
-
7/1/2008 - Conference papersThe centerpiece of this project is development of a Dynamic Failure Control Program to monitor evolution of dynamic failure hazards with changing geologic conditions to assure that control and protective measures are appropriately deployed.
