The constant mi in the Hoek-Brown (HB) criterion is a fundamental parameter required for
determining the compressive strength of rock. In this paper, drilling parameters provide a …

Rock strength parameters are substantially impacted by porosity. This paper proposes a
new model for presenting the relationship between porosity and the ratio of the unconfined …

In mining excavation, the roof bending subsidence of gob-side entry driving heading
adjacent to the advancing working face (HAWF) can be considerable. Influenced by the …

When slopes are excavated in rock masses with the blasting method, blasting and stress
relaxation will produce an excavation damage zone (EDZ) in the remaining rock mass. This …

The constant mi is a fundamental parameter required in the Hoek–Brown (H–B) failure
criterion for estimating rock strength. Triaxial tests for the calculation of this constant are time …

The shear strength of rock fractures serves as a crucial control on the strength and
deformation behavior of engineering rock masses. To reduce the uncertainties in the shear …

Rock strength is imperative for the design and stability analysis of engineering structures.
The Mohr–Coulomb (MC) criterion holds significant prominence in geotechnical …

To study the fracturing mechanism and deformation characteristics of the rock surrounding
the gate during gob-side entry retention through roof pre-fracturing, the roof fracture laws …

The strength criterion of rock is essential for stability control and safety design of
geotechnical engineering constructions. Due to its widespread adoption, the Mohr–Coulomb …

The crack closure effect of rock materials plays a key role in the evaluation of its
compressive mechanical behavior. Based on the effective medium theory, an exponential …
