The nonlinear stability control of surrounding rock with large deformation is the key issue in
realizing rapid excavation of deep soft rock roadway. Combined with various research …

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 …

Fully grouted cable bolts have been used in the mining industry for many decades. To
understand their mechanical performance, numerous laboratory pull-out tests have been …

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 …

By now, various accelerators have been used to accelerate the chemical reactions between
cement and water to achieve a desired strength. This study investigates the effects of …

A new series of double shear tests were carried out using a newly modified double shear
apparatus which prevented contacts between concrete block surfaces during shearing. 13 …

Anchor cables often break in various forms. Tensile failure can be resisted by using high-
strength materials, while there is no good solution for shear failure. A new supporting …

The embedment length (EL) of full-grouting rock bolts is a core factor in rock bolt
reinforcement. Therefore, understanding the influence of EL on the reinforcement …

A new laboratory short-encapsulation pull test was developed to better understand load
transfer behavior of fully grouted cable bolts that are commonly used in underground mines …
