Due to its complexities, rock fracturing process still poses many pressing challenges despite
intense research efforts. With the rapid development of computational mechanics, numerical …

A state-of-the-art review is conducted to highlight the fracture mechanism in rock blast and
advantages and limitations of various methods in modelling it. A hybrid finite-discrete …

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

In rock blasting, the effect that stress wave superposition between boreholes has on rock
fragmentation remains controversial. Here, we experimentally study the stress wave …

Rock fragmentation by blasting is determined by the level and state of stress in the rock
mass subjected to blasting. With the application of electronic detonators, some researchers …

The paper presents a methodology for the calibration of a Karagozian-Case Concrete (KCC)
constitutive model for the simulation of dolomite rock. A series of basic experiments are …

Optimizing blasting parameters is a crucial and challenging aspect for mines to enhance
production efficiency and ensure safe operations. Effectively controlling the distribution …

With the application of electronic detonators, millisecond blasting is regarded as a significant
promising approach to improve the rock fragmentation in deep rock blasting. Thus, it is …

This paper presents a procedure to compute the parameters of the Karagozian and Case
Concrete (KCC) constitutive model for brittle materials based on dolomite rock. First, the …

The effect of inter-ring delay time (IRDT) on rock fragmentation in the tunnel excavation
blasting was studied at the Xinjiang Beizhan Iron Mine, China, to improve the rock …
