Underground coal mining is characterized by the formation of extensive pillars. Coal pillars
serve various purposes, and their instability failure characteristics play a vital role in safety …

A large number of abandoned mines with sizeable underground space resources were
formed in China. Meanwhile, for an operational mine, the protection and utilization of mine …

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 …

Flooded mine workings represent potential aquifers for shallow geothermal development
projects. However, determining the collapse state of such workings in advance of drilling …

In order to enhance the ability to represent rock feature information and finally improve the
rock identification performance of convolution neural networks (CNN), a new pooling mode …

To further study the load transfer mechanism of roof–multi-pillar–floor system during
cascading pillar failure (CPF), numerical simulation and theoretical analysis were carried out …

Abstract Knowledge of the uniaxial compressive responses of rock mass is crucial for
evaluating the stability of rock pillar in underground engineering. The inherent spatial …

Pillars are important structural elements that provide temporary or permanent support in
underground spaces. Unstable pillars can result in rock sloughing leading to roof collapse …
