In backfill mining, the surrounding rock is dynamically damaged by intermittent mining and
blasting. After backfilling, bleed water from the backfill seeps into the surrounding rock …

Constructing pumped-storage power stations using underground reservoirs in mines offers a
promising method for large-scale energy storage. Watertight coal pillars have the potential to …

To explore the static mechanical and damage evolution characteristics of hot dry rock,
groups of uniaxial compression test and Brazilian splitting test were performed on granite …

We characterized the strength and deformability of Wuyi granite based on Brazilian tests and
axisymmetric compression tests under different confining pressures (0, 5, 10, 20, 25, and 30 …

High-temperature conditions in current deep-earth engineering predominantly hover within
the 300° C mark. While several studies have shown granite and marble to display thermally …

The instability failure of engineering rock mass is caused by the full development of cracks
under the combined action of the surrounding rock stress environment and frequent stress …

The ultrasonic characteristics of the coal and rock bodies around boreholes during failure
are closely related to the crack propagation law. To investigate the ultrasonic characteristics …

Cemented gangue backfill technology is an important backfill mining method. However, the
acid mine water environment could seriously affect the strength of the cemented gangue …

This study provides valuable insights into the damage patterns and fracture mechanisms of
travertine and marble, two rocks widely utilized for various applications. Given the strong …
