This paper presents a review of the existing models for the estimation of explosion-induced
crushed and cracked zones. The control of these zones is of utmost importance in the rock …

Using ring-shape specimens containing two aligned cracks on the internal surface of the
ring, two test configurations subjected to tensile or compressive loads namely (i) …

High in-situ stress can limit the generation of rock fractures induced by blasting, which
usually shows different states of rock fragmentation with those under low-stress conditions …

To study the rock-breaking mechanism resulting from high-pressure gas blasting, a hybrid
continuum-discontinuum method considering the actual breakage of rocks was presented in …

This paper aims to study the fracture characteristics of blunt indenter impacting formation
under static and harmonic dynamic loads by carrying out a series of FE numerical …

Advancements in recent shale gas development technologies like creating hydraulic
fracturing have greatly improved the production of unconventional shale gas reservoirs …

Since the invention of electronic detonators with a delay accuracy within 1 ms, short-delay
blasting technology has been used in mining and tunnelling engineering to improve rock …

Heterogeneous brittle geomaterials are highly susceptible to cyclic loads. They contain
inherent flaws and cracks that grow under fatigue loads and lead to failure. This study …

The mechanical heterogeneity of unconventional gas reservoirs is a significant factor
affecting the nucleation and propagation of hydraulic fractures. The ignorance of mechanical …

Soundless cracking demolition agent (SCDA) as an environment-friendly rock fracturing
material has been subjected to many physical experiments, but numerical simulation …
