• Diagnosing and Controlling Moisture-Sensitive Roof in Coal Mines
  1/1/2008 - Peer reviewed journal articles
  Moisture-sensitive roof rocks have contributed to time-dependent roof falls. NIOSH research proves the value of a wet/dry cycling test for rock evaluation.
• Experimental Study on the Confinement-Dependent Characteristics of a Utah Coal Considering the Anisotropy by Cleats
  5/1/2018 - Peer reviewed journal articles
  A study in which laboratory testing was used to identify the engineering characteristics and brittleness of coal samples.
• Applying Robust Design to Study the Effects of Stratigraphic Characteristics on Brittle Failure and Bump Potential in a Coal Mine
  1/1/2018 - Peer reviewed journal articles
  An article describing the results of a robust design to consider the impact of different lithologic risk factors impacting dynamic failure risk.
• Identification of Areas at Risk for Coal Bursts in Deep Cover Room and Pillar Mines
  10/22/2016 - Research projects
  A project to define the geologic and stress criteria associated with an elevated risk of coal bursts, considering both U.S. and international experience through visits to coalfields.
• Building Capacity and Enhancing Ground Control Safety through Improvement and Extension of the LaModel Program
  7/16/2016 - Contracts and cooperative agreements
  A capacity-building contract to enhance ground control safety and produce qualified MS and PhD graduates with ground control expertise through improving and extending the LaModel program.
• The Role of Gas Desorption in the Energetic Failure of Coal
  3/4/2014 - Contracts and cooperative agreements
  A contract to evaluate the role of gas desorbing on the failure of coal and the resultant influence on dynamic failures such as bumps, bursts, and outbursts.
• Regional Bumps: Case Studies from the 1958 Bump Symposium
  1/1/2010 - Peer reviewed journal articles
  This paper looks at historical descriptions of bumps with regional scale, in the hope that by investigating dynamic failure modes with potential to create the next disaster, that disaster might be averted.
• Coal Bumps and Odd Dynamic Phenomena - A Numerical Investigation
  7/1/2009 - Conference papers
  This study extends the method of dynamic analysis to events driven by slip on geologic features.
• Deep Cover Pillar Recovery in the US
  7/1/2009 - Conference papers
  This paper provides an overview of current deep cover pillar recovery practice.
• Dynamic Failure in Deep Coal: Recent Trends and a Path Forward
  7/1/2008 - Conference papers
  The centerpiece of this project is development of a Dynamic Failure Control Program to monitor evolution of dynamic failure hazards with changing geologic conditions to assure that control and protective measures are appropriately deployed.
