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.
