With the shallow resources dwindling, many countries have entered into deep mining one
after another. Rock fracture caused by high stress mining disturbances is a significant …

To analyze and predict the mechanical behaviors of deep hard rocks, some key issues
concerning rock fracturing mechanics for deep hard rock excavations are discussed. First, a …

Excavation-induced disturbances in deep tunnels will lead to deterioration of rock properties
and formation of excavation damaged zone (EDZ). This excavation damage effect may affect …

In underground mining, especially in entry-type excavations, the instability of surrounding
rock structures can lead to incalculable losses. As a crucial tool for stability analysis in entry …

This study used a three-dimensional model based on the finite-discrete element method-
smoothed particle hydrodynamics (FDEM-SPH) coupling approach to reconstruct the 11 …

The deep surrounding rock is in a three-directional stress state before mining. The process
of roadway excavation is the process of confining pressure unloading due to the …

To efficiently link the continuum mechanics for rocks with the structural statistics of rock
masses, a theoretical and methodological system called the statistical mechanics of rock …

Tunnel excavation by cyclic blasting caused accumulative damages to the surrounding
rocks, reducing the intactness of the rock mass. The blasting impact contributes to the …

The tensile strength of rock is a crucial parameter for the stability assessment and
reinforcement design of rock engineering, which is commonly determined by indirect tension …

Drill and blast method is widely applied in deep rock engineering, and the in-situ stress
poses a great challenge to blasting excavation. The failure mechanism of rock under …
