Effects of elevated ground temperatures on properties of cement grouts for deep rock grouting

Deep Underground Science and Engineering, EarlyView.
When the temperature is up to 35°C, significant improvement in rheological parameters, acceleration of grout setting, and an increase in the rheological time dependence of thick cement grout can occur, but there may be a slight effect on the initial grout flowability and the nature of shear thinning.

Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC

Deep Underground Science and Engineering, EarlyView.
This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

A comprehensive review of experimental studies on shear behavior of bolted rock joints with varying rock joint and bolt parameters and normal stress

Deep Underground Science and Engineering, EarlyView.
This study reviews the research findings on the shear behavior of bolted rock joints in deep underground engineering, where they face high stress, high water pressure, and engineering disturbance. This study examines how the shear strength of bolted rock joints is affected by various factors, such as normal stress, rock compressive strength, joint ...

Experimental study on the damage characteristics of cyclic disturbance and acoustic emission characteristics of different types of sandstones under high stress in deep mines

Deep Underground Science and Engineering, EarlyView.
The mechanical characteristics of three different types of sandstones under high stress levels are studied. The degree of fragmentation of specimens increases with the applied stress level. The acoustic emission counting of different types of sandstones presents three stages: weakening, stabilizing, and surging.
