10/1/2009 - Conference papersThe objective of this research is to estimate the cementitious seal/rock interface properties from full scale test results.
-
5/1/2004 - Conference papersResearchers are investigating the causes and mechanisms of roof failure in underground mines with the goal that better understanding these issues will lead to better layout and support designs to help prevent fall-of-ground accidents and fatalities.
-
6/1/2003 - Conference papersThe authors hypothesize that excavation-induced extension fractures are caused by elastic shearing displacement that in turn causes tension oblique to a propagating shear zone.
-
3/1/2000 - Conference papersA NIOSH study of the time-dependent response of rock stressed along weakness planes with the objective to improve mine safety by reducing the number of roof falls that cause injuries and fatalities to miners.
-
1/1/2000 - Conference papersThis study reviewed 31 technical papers that analyze shear strengths for clay and sands containing rock particles. Results show that shear strength gradually increases with increasing percentages of floating particles in unsaturated clays.
-
8/1/1999 - Conference papersRecent studies by researchers from the National Institute for Occupational Safety and Health indicate that shear loading contributes significantly to failure of bolts used for rock reinforcement in coal mine roofs. Laboratory tests on 17 bolts were con...
