• CFD Modeling of Fire Spread Along Combustibles in a Mine Entry
  3/1/2006 - Conference papers
  A 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.
• Operationalizing Normal Accident Theory for Safety-Related Computer Systems
  11/1/2005 - Peer reviewed journal articles
  Normal 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.
• Computer Simulation of Ground Behaviour and Rock Bolt Interaction at Emerald Mine
  8/1/2004 - Conference papers
  This 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.
• Applications of the Point Estimation Method for Stochastic Rock Slope Engineering
  6/1/2004 - Conference papers
  The 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.
• Analysis of Bench Crest Performance at the Yellowstone Mine: A Case Study
  5/1/2004 - Conference papers
  A 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 States
  8/1/2003 - Conference papers
  This 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.
• Rock Damage Characterisation from Microseismic Monitoring
  7/1/2001 - Conference papers
  Outlines 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.
• Evaluation of VR Mine Rescue Training Platform
  11/14/2023 - Research projects
  A project to evaluate NIOSH’s recently developed VR Mine Rescue Training platform as a supplemental training tool.
• Development of Rib Brow Guideline and Integration into the Coal Pillar Rib Rating (CPRR) System
  7/10/2023 - Contracts and cooperative agreements
  A contract to enhance the safety of miners through new rib brow management strategies.
• AutonoDES: A Discrete Event Simulation Platform for Safety Scrutiny of Autonomous Mining Systems
  6/13/2023 - Contracts and cooperative agreements
  This contract research develops a simulation software platform, AutonoDES, that can be used as a “what-if” scenario analysis tool for mixed-fleet (both human-operated and autonomous) mining operations.
