Comparing Distributed Acoustic Sensing To Three-Component Geophones In An Underground Mine, Nikolas Nesladek
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
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.
The World Museum of Mining (Orphan Girl) and UMEC (Orphan Boy) facilities …
Mining Asteroids For Volatile Resources: An Experimental Demonstration Of Extraction And Recovery, Egboche Christopher Unobe
Mining Asteroids For Volatile Resources: An Experimental Demonstration Of Extraction And Recovery, Egboche Christopher Unobe
Masters Theses
"Gaseous compounds trapped within carbonaceous asteroids may prove to be important targets for prospective space miners in the near-term. Volatile release is from hydrated, hydroxylated and carbonated phases present, making such bodies attractive as feedstock for the production of H2O, CO2 and simple organic compounds. A source of these species in orbit provides an opportunity to locally produce space-craft propellant and other life-support gases through the application of In-situ Resource Utilization (ISRU).
For this study, an experimental vacuum system was modified and used to test the technical validity of radiatively heating asteroid simulants to extract contained gaseous …
