Tunnel blasting is a common practice used to excavate rock formations. Many academic
research articles have emerged and burgeoned in the field of tunnel blasting. These articles …

Blasting constitutes an essential component of the mining and construction industries.
However, the associated nuisances, particularly blast vibration, have emerged as significant …

Decoupled charge structures are widely used in contour blasting because of their lower
peak value and loading rate of the borehole wall pressure (BWP), which plays an important …

Decoupled cylindrical charge structure is widely used in contour blasting to reduce
overbreak and control rock damage, which is critical to the safety and efficiency of rock …

Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of
damage by quantifying micro-earthquakes in terms of time, location, grade, and energy …

During the numerical simulation of blasting in jointed rock masses, the accuracy of joint
geometric parameters is one of the key factors affecting the numerical results. To facilitate …

Deep mine rock mass is in high static stress and dynamic disturbance coupling conditions,
its mechanical properties and failure mode is different from the shallow rock mass, which …

The aim of this study was to investigate the optimization of cut-blasting methods for deep
rock masses under high in situ stress. Several plane fluid–structure interaction (FSI) models …

Underground rock masses are often exposed to dynamic disturbances due to seismic waves
and blasting excavation disturbances, resulting in significant changes in their physical and …

Accurately control the release of explosive energy is critical, the number of slit charge is the
key to control the precise release of explosive energy. By carrying out model experiments …
