As drilling and blasting technique is applied in deep mining, its practical performance with
respect to rock fragmentation becomes a serious concern because high in-situ stress …

This paper presents a peridynamics-based computational approach for modelling blasting
induced rock fractures. A new non-ordinary state-based peridynamics approach is proposed …

Blasting is widely applied in deep rock excavation. The effect of in-situ stresses on the
fracturing of rock due to blasting was investigated. A theoretical model was used to explain …

Understanding the behavior of rock under blast-and shock-induced loadings requires a high-
fidelity constitutive model. The present paper provides a detailed comparison study of three …

Ensuring the safety of adjacent pressure gas pipelines is a key issue in the blasting
excavation of foundation pits in complex urban environments. In this paper, the blasting …

Enhancing mine energy efficiency and productivity necessitates the implementation of
longer ore passes, exceeding 300 m, to optimise material transport in underground mass …

Abstract The original Holmquist-Johnson-Cook (HJC) model, which can only capture the
compressive behaviour but not the tensile behaviour of brittle materials, is modified in this …

To ensure the safety of gas pipeline during tunnel blasting excavation, it is crucial to
investigate the dynamic response of gas pipeline to blast vibration under tunnel excavation …

Controlling rock damage induced by lateral blasting excavation is a source of concern. In
underground mines, large-diameter-hole lateral blasting excavation often causes …

The block caving mining method has become increasingly popular in the last two decades.
Meanwhile, Indonesia has several potential ore bodies which have not yet determined …
