• The Ground Response Curve, Pillar Loading and Pillar Failure in Coal Mines
  7/1/2010 - Conference papers
  This paper makes use of numerical models to examine the interaction between typical pillar systems and the surrounding rock mass for weak and strong geological conditions at various spans and depths of cover.
• 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.
