Strainburst occurrence in underground mines is associated with highly stressed brittle and
stiff rockmasses which instantaneously dissipate excess strain energy. This strainburst …

Groundwater seepage can easily cause large deformation and fracture instability of the
surrounding rock in deep roadways, and the coupling support of “yield-bolt-grouting” can …

Understanding the failure mechanism and stability of pillars is necessary for their efficient
extraction in Airleg stopes (ALS). By substituting standing support structures that can sustain …

Strainburst is the most common type of rockburst which is encountered as a dynamic rock
failure mechanism in deep high stressed underground excavations (Cai 2019 …

Bolted-flange connected structure is widely used on Primary Equipment of Nuclear Power
Plant and it is one of the most important assemblies of Primary Coolant Loop. Special …

Bolts are un-permanent fasteners that are often used in machine assembly. The bolts are
tightened by drilling holes on the parts to be connected to each other and attaching a nut to …

Direct tension indicators (DTIs) are one alternative method that is commonly used to verify
that high-strength bolts have been properly tensioned during installation. This paper …
