A new protective destressing technique in underground

Deep underground hard rock mining has been experiencing the violent failure of rockburst for a while. Nowadays, coal mining suffers from a similar instability problem, which is coalburst, as a result of operating in extreme depths. As the problem arises from overstressing, some remedial measures have been developed to destress the rockmass.
