ABSTRACT
The paper deals with the testing of retainment support under dynamic conditions typical of the loading experienced during rockbursts. The testing was carried out for the following support types:
rebar type rockbolts;
yielding and smooth bar rockbolts;
splitset and Swellex rock bolts;
destranded hoist rope.
The dynamic testing method made use of test samples which attempted to simulate realistic in situ conditions, and the range of loading imposed using a drop weight system was equivalent to small to severe rockburst conditions.
