Interaction of powered supports and the strata in coal seams under a heavy roof
Summary The interaction of powered supports and the strata in thick coal seams under a heavy roof is discussed when subjected to anomalous phenomena, particularly rock bursts, which have occurred in the Upper Silesian Coal Basin in the last few years. On the basis of the results of long-term field measurements and theoretical analyses, the necessary setting and yield loads of powered supports as well as loading patterns which appear during rock bursts have been determined. A methodology for the testing of powered supports destined for coal seams prone to rock bursts, for the implementation of which a rapid closure rig should be built, is proposed.
