8/1/2003 - Conference papersA three-step method is presented to determine nonlinear stress-strain curves for boundary-element programs used in many mining applications. The method requires a suite of laboratory-scale strength tests at various confining pressures.
-
8/1/2003 - Conference papersThis paper utilizes rock-fall-related incident narratives from the MSHA database for a taxonomic analysis, which identifies event root causes and provides future direction for corrective measures to reduce the probability of event occurrence.

3/1/2001 - Information CircularsWorking in elevated areas near an edge is a common hazard for operators of off-highway mobile mining equipment. Serious injuries involving haulage trucks working at dump sites are examined for the period 1988 to 1997.
-
2/1/2001 - Conference papersOne recurring mine safety problem - a dozer falling into a void over a drawpoint on a coal surge pile - was analyzed using fault tree analysis software on a personal computer. The analysis identified basic and intermediate events that led to the burial ...

1/1/2001 - Catalogs and indexes, NIOSH/USBM numbered publicationsA listing of the mining-related publications produced by NIOSH from 1995 to 2000.
-
8/1/2000 - Conference papersResearch on techniques that will reduce the hazards in the mining workplace associated with coal bumps.
