Rockburst is becoming a huge challenge for the utilization of deep underground space.
Extensive efforts have been devoted to investigating the rockburst behavior and mechanism …

To investigate the influence of thermal treatment on the rockburst in granite caverns, true-
triaxial compression tests were conducted on pre-heated granite cubic samples containing a …

Rockbursts, as a kind of dynamic disaster that exists in tunnels for a long time, are of
incalculable harm, which may lead to huge human and economic losses and seriously …

Mechanical excavation, blasting, adjacent rockburst and fracture slip that occur during
mining excavation impose dynamic loads on the rock mass, leading to further fracture of …

The effect of high temperatures up to 800° C on the physical and mechanical characteristics
and fracturing behaviour of Beishan granite is experimentally studied with a combination of …

As a common disaster in deep-buried hard rock engineering projects, rock-bursts seriously
threaten the safety of workers and facilities. Water infusion in rock mass before excavation is …

Rockburst disasters occur frequently during deep underground excavation, yet traditional
concepts and methods can hardly meet the requirements for support under high geo-stress …

Biaxial compression tests were conducted on circular tunnels that constructed in sandstone
to reveal the evolution of macro-cracks, the strain field, and acoustic emission (AE) …

Investigation of unloading rock failure under different σ 2 facilitates the control mechanism of
excavation surrounding rock. This study focused on single-sided unloading tests of granite …

Rockburst phenomenon is the extreme release of strain energy stored in surrounding rock
mass which could lead to casualties, damage to underground structures and equipment and …
