• AHSM - Analysis of Horizontal Stress Effects in Mining
  8/20/2013 - PC software
  A software program to help improve mine layouts for control of horizontal stress.
• 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.
• Performance of Roof Support Under High Stress in a U.S. Coal Mine
  2/1/2004 - Conference papers
  The primary goal of this project was to obtain detailed data on the interaction between the mine roof and the support elements for use in modeling studies. 
• 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 Mechanics Study of Lateral Destressing for the Advance-and-Relieve Mining Method
  8/1/2003 - Conference papers
  The advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
• Safer Mine Layouts for Underground Stone Mines Subjected to Excessive Levels of Horizontal Stress
  4/1/2003 - Peer reviewed journal articles
  At an underground stone mine, a modified stress-control mine layout is reducing hazardous conditions associated with excessive horizontal stress. Findings show that the layout provides more stable conditions, resulting in a safer working environment.
• Advance and Relieve Mining: A Method to Mitigate the Effects of High Horizontal Stress on the Mine Roof
  2/1/2001 - Conference papers
  Evaluation of the "Advance and Relieve" mining method is described to determine effectiveness for conditions where high horizontal stresses caused long running roof falls resulting in hazardous conditions and the premature abandonment of panels.
• Utilizing the 'Advance and Relieve' Method to Reduce Horizontal Stress Affects on the Mine Roof, A Case Study
  1/1/2000 - Conference papers
  The practical application of the "advance and relieve" method is discussed. A trial of the method was conducted for a room and pillar coal operation that was experiencing roof cutters and long running roof falls caused by high horizontal stresses.
• Controlling Roof Beam Failures From High Horizontal Stresses in Underground Stone Mines
  8/1/1998 - Conference papers
  A design technique is presented which provides stone miners with a method for making stability assessments. The consequences of widening rooms, changing geology and horizontal stresses, and different rock bolts on roof beam failure are discussed.
• Horizontal Stress and Longwall Headgate Ground Control
  1/1/1998 - Peer reviewed journal articles
  Horizontal stresses are caused by global plate-tectonic forces. This paper presents six case histories of mines that encountered roof falls or difficult ground conditions at the headgate caused by horizontal-stress concentrations.
