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 …

With increasing coal mining intensity, the number, length and depth of coal mine roadways
is increasing drastically, the traditional drill-&-blast method and comprehensive mechanized …

The rock failure process is associated with acoustic emission (AE). Hence, violent rock
failure processes such as rock burst under different stress paths in laboratory can be studied …

This paper describes synthetic rock mass (SRM) modeling, a new approach for simulating
the mechanical behavior of jointed rock mass. This technique uses the bonded particle …

Many factors that influence rockburst damage have been identified but the mechanism that
drives rockburst is not fully understood. Weak planes such as faults and shears have been …

A theoretical formulation was first established to evaluate the dynamic stress concentration
factor (DSCF) around a circular opening under conditions of blasting stress wave incidence …

The nonlinearity of rock becomes more significant as the buried depth increases, which
changes the stress redistribution and deformation patterns during tunneling. In this study, a …

In the present study, structural model test using rectangular prismatic granite specimen 200
mm× 200 mm× 200 mm with a horizontal central circular hole of 78 mm diameter was …

The method of cut blasting is widely used in tunnelling excavation, which concerns the
success in subsequent stop blasting and smooth blasting. Rock masses in deep tunnels are …

Rockburst is a sudden and violent failure of rocks and it often occurs in hard rocks in highly
stressed ground. Strainburst is classified as one type of rockburst and it often occurs in rocks …
