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.

Temperature And Pressure Sensing In Three Flooded Underground Mine Workings In Butte, Montana, Usa, Tyler Hagan

Graduate Theses & Non-Theses

Temperature and pressure were measured in several flooded underground mine shafts in order to assess the potential for the development of additional mine-based geothermal heating in Butte, Montana, USA. Temperature was sensed using both optical fibers, functioning as a distributed sensor, and thermistors, functioning as point sensors; while pressure was sensed using a piezoresistive strain gauge. Upon observing good agreement between the continuous and discrete temperature sensors, we found no significant change in temperature with increasing depth within the water column. This suggests the thorough transfer of heat throughout the mine shaft via convection. Moreover, we found water temperature (T) …
