Mining Contract: Building Capacity and Enhancing Ground Control Safety through Improvement and Extension of the LaModel Program
This contract will result in numerous improvements and extensions to the LaModel program.
Contract Status & Impact
Stable underground mine openings are fundamental to providing a safe work environment. Unfortunately, underground mining has one of the highest fatal injury rates of any U.S. industry, and ground failures are the single largest source of those fatalities. During the past decade, approximately 40% of underground mining fatalities were caused by roof falls, rib collapses, or bumps/bursts. In addition, approximately 600 miners are non-fatally injured (often severely) every year by rock falls in coal mines. Yet, the number of mining professionals with expertise in mine ground control engineering has declined significantly over the past few decades.
This project will enhance ground control safety and produce qualified MS and PhD graduates with ground control expertise by accomplishing research tasks that improve and extend the LaModel program. The LaModel program is used to model the stresses and displacements on thin tabular deposits such as coal seams. Over the last two decades, LaModel has been used by many mine engineers and researchers for improving pillar designs and mine safety in single seam analysis, multiple-seam analysis, subsidence prediction, bump analysis, overall mine stability analysis, and many other instances.
