• Building Capacity and Enhancing Long-Term Coal mine Weak Roof Stability through Characterization and Modeling of Time-Dependent and Moisture-Sensitive Failure in Shale
  9/18/2020 - Contracts and cooperative agreements
  A capacity building contract with Penn Sate University.
• Stability Evaluation of Active Gas Wells in Longwall Abutment Pillars
  9/16/2020 - Research projects
  A project to evaluate and quantify subsurface overburden deformations in longwall abutment pillars under shallow overburden depths, and to employ field instrumentation results and 3D numerical modeling to identify critical parameters.
• Transport Model for Shale Gas Well Leakage Through the Surrounding Fractured Zones of a Longwall Mine
  9/1/2020 - Peer reviewed journal articles
  An article presenting an analytical model of gas transport through fractures in a low permeable stratum.
• Shale Failure Mechanics and Intervention Measures in Underground Coal Mines: Results from 50 Years of Ground Control Safety Research
  2/1/2016 - Peer reviewed journal articles
  A report presenting a historical narrative on the research the National Institute for Occupational Safety and Health has conducted in relation to rock mechanics and shale.
• Identifying Moisture Sensitive Roof Rocks in Coal Mines
  8/1/2006 - Conference papers
  NIOSH conducted wet/dry immersion cycling of clay-rich rocks, which provides an accurate, quick and inexpensive method for estimating the moisture sensitivity of mudrocks. With this information mine operators can begin to anticipate hazardous ground.
