Technical challenges have always been part of underground mining activities, however,
some of these challenges grow in complexity as mining occurs in deeper and deeper …

Extreme ground behaviour in high-stress rock masses such as rockburst prone and
squeezing ground conditions are encountered in a range of underground projects both in …

Strain rockburst poses a great threat to the construction safety of deep engineering,
especially induced by dynamic impact loads such as blasting from the adjacent tunnel …

Rockburst seriously threatened construction safety of deep traffic tunnel in high geostress
condition. In recent years, a large number of deep traffic tunnels have been constructed in …

The structural planes adjacent to the tunnel have a significant effect on rockburst, which has
become an important engineering issue. To investigate the influence of such a rigid …

Natural geological structures in rock (eg, joints, weakness planes, defects) play a vital role in
the stability of tunnels and underground operations during construction. We investigated the …

Excavation-induced disturbances in deep tunnels will lead to deterioration of rock properties
and formation of excavation damaged zone (EDZ). This excavation damage effect may affect …

The occurrence of disasters in deep mining engineering has been confirmed to be closely
related to the external dynamic disturbances and geological discontinuities. Thus, a …

This paper documents investigations of the fatigue behaviour of strong burst-prone coal in
terms of energy dissipation, hysteresis and micro-seismicity. The energy dissipation …

Rockburst is a typical rock failure which frequently threatens both human life and
construction equipment during highly stressed underground excavation. Rock lithology is a …
