Effects of overburden characteristics on dynamic failure in underground coal mining

Dynamic failures, or “bumps”, remain an imperative safety concern in underground coal mining, despite significant advancements in engineering controls. The presence of spatially discrete, stiff roof units are one feature that has been linked to these events. However, an empirical stratigraphic revie...
