1/1/2020 - Peer reviewed journal articlesA study of the loading characteristics of mechanical bolts (stiffness and capacity) installed in coal ribs at five underground coal mines.
-
1/1/2020 - Peer reviewed journal articlesAn article detailing observations of the non-typical bleeder entries of a moderate depth longwall panel, with a primary focus on the extent and magnitude of the abutment loading.
