3/1/2006 - Conference papersA computational fluid dynamics (CFD) program was applied to fire spread along combustibles in a ventilated mine entry. The rate of flame spread was evaluated for the ribs and roof of a coal mine entry, timber sets, and a conveyor belt.
11/1/2005 - Peer reviewed journal articlesNormal Accident Theory is a classic argument in organizational sociology, although it has been criticized as having imprecise definitions and lacking criteria for quantifying complexity. These limitations are addressed by a unique approach.
8/1/2004 - Conference papersThis paper focuses on a computer simulation used to model roof behavior and rock bolt interaction in a collaborative study of ground behavior, reinforcement performance, and stress redistribution in a coal mine entry under severe horizontal stress.
6/1/2004 - Conference papersThe point estimation method for the probability of sliding is efficient and expedites slope stability simulation routines in NIOSH software to stochastically describe rock slope behavior and assist engineers in catch bench design for large slopes.
5/1/2004 - Conference papersA case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
Variation of Horizontal Stresses and Strains in Mines in Bedded Deposits in the Eastern and Midwestern United States8/1/2003 - Conference papersThis paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
7/1/2001 - Conference papersOutlines the concepts used to correlate rock failure with microseismic events and presents examples of microseismic monitoring together with associated computer modeling of the rock failure from several mine sites.
Design of an Optically Accessible Scaled-Version of a Longwall Coal Mine for Investigating Explosion Hazards3/25/2020 - Contract reportsA contract to build a 1/40th scale model of a longwall coal mine.
1/1/2020 - Peer reviewed journal articlesThe article presents seven cases of conventional gas wells within chain pillars and discusses how numerical modeling can provide a more quantifiable approach to assess the stability of the gas wells.
1/1/2020 - Reports of InvestigationsThis part 2 of a two-part series describes ground stress in mining by calibrating and verifying longwall stress models.
