• Seismic Network Operations at a Deep Underground Coal Mining District in Western Colorado (USA)
  8/1/2009 - Conference papers
  This paper describes network installation and methods used to collect, process, and distribute seismicity information collected on the surface above two longwall coal mines in western Colorado, and gives several examples of the collected data.
• Monitoring Coal Mine Seismicity with an Automated Wireless Digital Strong-Motion Network
  7/1/2008 - Conference papers
  This paper describes a seismic network installed in western Colorado in the vicinity of three underground coal mines, its features for user access to data, and then gives two examples of seismic events resulting in some damage to mine workings.
• 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.
• Microseismic Activity Associated With a Deep Longwall Coal Mine
  2/1/2002 - Conference papers
  A deep longwall coal mine was instrumented with a 3-D microseismic system to help determine the exact strata mechanics associated with rock failure, redistribution of stress and associated gob formation from the longwall.
• Rock Damage Characterisation from Microseismic Monitoring
  7/1/2001 - Conference papers
  Outlines the concepts used to correlate rock failure with microseismic events and presents examples of microseismic monitoring together with associated computer modeling of the rock failure from several mine sites.
• Evaluation of Seismic Potential in a Longwall Mine with Massive Sandstone Roof Under Deep Overburden
  7/17/2018 - Peer reviewed journal articles
  An article describing the development of seismic forecast maps based on the geology of previous seismic locations.
• Advanced Mining Seismicity Processing
  3/30/2017 - Research projects
  A project to explore and refine advanced event detection, location, and magnitude estimation methods that can be used to increase seismic catalog quality.
• Passive Seismic Tomography for Monitoring Stress Redistribution at the Galena Mine
  11/21/2016 - Contracts and cooperative agreements
  A contract on passive seismic tomography for monitoring stress redistribution at the Galena Mine.
• Coal Mine Safety Applications of Seismic Monitoring
  10/22/2016 - Research projects
  A project to implement in-mine seismic monitoring techniques in coal mines to evaluate and demonstrate potential mine safety benefits of this technology.
• Seismic Monitoring Strategies for Deep Longwall Coal Mines
  9/1/2016 - Reports of Investigations
  A Report of Investigations presenting five strategies for detecting and recording seismic activity associated with deep longwall coal mining.
