Technical challenges have always been part of underground mining activities, however,
some of these challenges grow in complexity as mining occurs in deeper and deeper …

The design of underground hard rock pillars plays a crucial role in the safety and stability of
underground mining operations. Ensuring safe and efficient resource extraction while …

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 …

Strain burst occurs within highly stressed hard rocks in underground excavations. A
prerequisite for strain bursting is that excess energy exists to eject material after rock failure …

Rockburst is a common geological disaster in the process of deep rock excavation, and
stress gradient is an important factor affecting rockburst. In this paper, the concept of “stress …

Seismic disturbances frequently trigger or induce violent strainbursts, threatening regular
operations and personnel safety in deep underground excavation. We reproduce the cyclic …

The increasing demand for resources and depletion of near ground mineral resources
caused deeper mining operations under high-stress rock mass conditions. As a result of this …

In general, the strength of rock and rock mass is non-linearly associated with the confining
stress. Thus, the non-linear Hoek–Brown strength criterion (Hoek and Brown 1980, 1982) is …

This work presents the spatio-temporal variations of microcracking and damage
accumulation during the progressive failure in a low-porosity sandstone under uniaxial …

Pillars are often reserved asymmetrically in the mining process. The roof deflection curve
under non-equal span conditions of adjacent stopes is derived by considering the roof-pillar …
