Advanced Computing and Sensing to Improve Mine Fire Characterization and Response
After fire is discovered in an underground coal mine, a decision must be made to mitigate fire consequences. The decision should be made based on existing conditions, with the goal of increasing the probability of fire extinguishing without compromising the health and safety of the firefighting …

The Measurement of Decomposition Products of Select Gases as an Indicator of a Concealed Mine Fire
Currently, techniques used to determine whether or not there is a concealed fire in an inaccessible area of a coal mine are not definitive. Inaccessible areas of coal mines include: 1. A mined-out area, such as a long-wall gob. 2. A mine area, or entire mine, that has been sealed to extinguish a …

Development of Potential Remote Coal Mine Fire Response Measures: Use of Multiple Passive Source Tracers and Simulation of High Expansion Foam Flow in Simulated Gob Material
This thesis examines potential improvements to current coal mine fire response measures. In the event of a fire scenario, indirect testing and analysis of the exhausting air is needed to characterize changes in the fire. The application of multiple passive source tracers provides improved detail of …

Fire Simulation Cost Reduction for Improved Safety and Response for Underground Spaces
… strides have been made in the advancement of mine fire knowledge since the 1909 Cherry Mine Fire Disaster, one of the worst in U.S. history. However, fire hazards remain omnipresent in underground coal mines in the U.S. and around the world. A precise fire numerical analysis (simulation) …

Into the Into of Earth Itself
… condemned and evacuated due to an underground mine fire, which will continue for another 200 years. The manuscript uses visual forms and digital text mining techniques to craft poetry about these extractive relationships to land and women. The speaker asks herself: As a woman, how have I also …

Application of water mist to fuel-rich fires in model coal mine entries
… with higher mechanization, the way in which mine safety is approached must also change. This situation was clearly shown in a very devastating coal mine fire in late 1984. In the absence of effective fire-fighting procedures and equipment the affected mine was quickly rendered helpless. Of …

An Implementation-Based Exploration of HAPOD: Hierarchical Approximate Proper Orthogonal Decomposition
Proper Orthogonal Decomposition (POD), combined with the Method of Snapshots and Galerkin projection, is a popular method for the model order reduction of nonlinear PDEs. The POD requires the left singular vectors from the singular value decomposition (SVD) of an n-by-m "snapshot matrix" S, each …
