• Alternative Mining Methods in Challenging Environments
  9/16/2020 - Research projects
  A project to reduce injuries and fatalities caused by rockburst-related ground failures in underground mines by developing an integrated, systematic approach for monitoring mining-induced seismic events.
• Two Sister Reports of Investigations on Ground Stress Research
  7/29/2020 - Publications
  Two Reports of Investigations provide detailed findings on ground stress redistribution resulting from mining, which could ultimately lead to significant improvements in the stability of mine excavations and ensure a safer working environment for miners.
• 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.
• Geologic Data Collection and Assessment Techniques in Coal Mining for Ground Control
  1/1/2020 - Peer reviewed journal articles
  An article covering geologic exploratory methods, data organization, and the value of collecting and interpreting geologic information in coal mines to enhance safety and production.
