Presenter: Ted M. Klemetti, Research Mining Engineer, Ground Control Branch, NIOSH, Pittsburgh, PA

Ground control failures continue to be one of the leading causes of injuries and fatalities in underground coal mining. The roof, rib, floor and pillars are four areas of potential ground failures that miners, engineers, and consultants are continually evaluating. Quite often, these four underground structures are evaluated independently. Several studies using field observations and instrumentation show that these relationships can be independent at times, while being dependent in other scenarios. The presented cases in this webinar demonstrate the importance of understanding the geological environment and mine design to ensure that the proper support is installed.
