As the depth of excavation increases, rockburst becomes one of the most serious geological
hazards damaging equipment and facilities and even causing fatalities in mining and civil …

To estimate the energy storage and release performances of rock pillars in high stress and
gain insights into the prevention and control of rockburst hazards from an energy aspect …

To deeply understand the failure characteristics of defective rock under actual stress
condition, impact tests were conducted on prismatic granite containing two rectangular holes …

The mechanical behavior of deep rock pillars is closely related to the coupling effect of the
initial high stress and the excavation-unloading process. In this study, the failure and …

To systematically assess the rockburst proneness considering specimen shape, multiple
groups of laboratory tests were performed on 5 rock materials in cylindrical and cuboid …

In this study we explore the use of a novel numerical modelling approach to study the effect
of pillar reinforcement on pillar stability. Case studies in the literature indicate that tendons …

A simple empirical time-dependent chart of extension fracture initiation is described. The
chart was developed using simple borehole periscope observations within the rib pillars …

abstract Geological storage of acid gas has been identified as a promising approach to
reduce atmospheric carbon dioxide (CO2), hydrogen sulfide (H2S) and alleviate public …

Rockburst is a sudden rock failure characterized by the breaking up and expulsion of rocks
from their surroundings, accompanied by a violent release of energy. Due to its …

The understanding of yielding pillar behavior has been well documented in terms of pillar
strength. The behavior has been documented using numerical simulations and empirical …
