As rock bursts are unavoidable in deep mines and excavations with high in-situ stresses,
ground support systems are implemented to manage and mitigate rock bursts. Cable bolts …

In this paper, after determining an appropriate experimental design and testing scheme to
test the shear performance suitably, the impacts of pretension and shear interfaces on …

A newly developed double shear apparatus without contact between concrete blocks was
developed to conduct a series of double shear tests. This new double shear apparatus is …

Pretension is the pre-added axial tensile force on fully grouted bolt systems, which include
rock bolts and cable bolts. Although a series of studies via lab testing and analytical …

Designing reliable yielding support system to mitigate the effect of the kinetic energy in burst-
prone conditions in mining and tunneling excavations is one of the challenges for …

Dichlorodiphenyltrichloroethane (DDT) is a recalcitrant synthetic chemical that threatens the
environment. Despite being banned in most industrialized nations, DDT is still used as a …

This paper aims to enhance the understanding of conventional rock bolt performance
subjected to shear loading under static and in particular dynamic loading conditions. For this …

As an effective and economical reinforcement method, end anchorage cables are widely
used for roadway support in coal mines. The failure of the free section of the end-anchored …

A set of single shear tests on fully encapsulated cable bolts was carried out using a newly
developed and integrated Megabolt single shear apparatus. The instrument is designed to …

To analyse the influence of normal stress (σ n) and steel tube strength on an anchor cable
with a C-shaped tube (ACC), we selected Q235 steel tubes and Q345 steel tubes as …
