Comparing Distributed Acoustic Sensing To Three-Component Geophones In An Underground Mine, Nikolas Nesladek Jul 2017

Comparing Distributed Acoustic Sensing To Three-Component Geophones In An Underground Mine, Nikolas Nesladek

Graduate Theses & Non-Theses

Geophones have become the industry standard for seismic data collection. However, a relatively new method is gaining popularity called Distributed Acoustic Sensing (DAS). DAS uses changes in backscattered light of a fiber-optic cable to detect strain from acoustic energy. The purpose of this project was to make a direct comparison between DAS and three component geophones, specifically in a mining setting. Experiments were done in the Underground Education Mining Center on the campus of Montana Tech. The sources used for this project were vertical sledgehammer shots, oriented shear sledgehammer shots, and blasting caps set off in both unstemmed and stemmed ...


Characterization Of Granite And Subsequent Ground Control Management Plan At Orphan Boy Mine – Butte, Montana, Emily Rose Apr 2017

Characterization Of Granite And Subsequent Ground Control Management Plan At Orphan Boy Mine – Butte, Montana, Emily Rose

Graduate Theses & Non-Theses

The Underground Mine Education Center (UMEC) and World Museum of Mining facilities began as shallow underground mines in the 1880’s during the mining boom that populated Butte, Montana. The UMEC is a multi-disciplinary facility that provides an on-campus underground laboratory environment and a place for students to learn and practice practical underground mining techniques; therefore, the longevity of the facility is important to Montana Tech. The goal of this project is to develop a Ground Control Management Plan (GCMP) for the UMEC and World Museum of Mining facilities.
