8/1/2009 - Conference papersThis 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.
7/1/2008 - Conference papersThis 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.
4/1/2003 - Peer reviewed journal articlesAt 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.
2/1/2002 - Conference papersA 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.
7/1/2001 - Conference papersOutlines 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 Overburden7/17/2018 - Peer reviewed journal articlesAn article describing the development of seismic forecast maps based on the geology of previous seismic locations.
3/30/2017 - Research projectsA project to explore and refine advanced event detection, location, and magnitude estimation methods that can be used to increase seismic catalog quality.
11/21/2016 - Contracts and cooperative agreementsA contract on passive seismic tomography for monitoring stress redistribution at the Galena Mine.
10/22/2016 - Research projectsA project to implement in-mine seismic monitoring techniques in coal mines to evaluate and demonstrate potential mine safety benefits of this technology.
9/1/2016 - Reports of InvestigationsA Report of Investigations presenting five strategies for detecting and recording seismic activity associated with deep longwall coal mining.
