• Design Procedures for Gateroad Ground Control
  3/4/2020 - Research projects
  A project to develop engineering-based procedures that will contribute to the practical design of ground control systems in gateroad excavations and longwall extractions.
• Analysis of ARMPS2010 Database with LaModel and an Updated Abutment Angle Equation
  1/1/2020 - Peer reviewed journal articles
  A paper presenting a new equation for calculating accurate abutment angles for deeper mining cases. The new equation was tested using both ARMPS2010 and LaModel for the entire case history database of ARMPS2010.
