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 …

The two most frequently heard terms in the mining industry are safety and production. These
two terms put a lot of pressure on blasting engineers and crew to give more while …

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 …

In this study, the tomography of dynamic stress coefficient (TDSC) was established based on
a mechanical model of stress wave propagation in bedding planes and a mathematical …

Various methods have been proposed to ensure the serviceability of buried structures such
as road tunnels, urban utility tunnels, water conduits, underground shelters, and deposition …

In the process of drilling and blasting in deep underground engineering, in situ stress is
usually considered as an essential factor for blasting parameter design. To explore the effect …

A theoretical method to predict underground tunnel behavior considering the peak particle
velocity (PPV) and the stress distribution is presented in this study. The influence of …

The previous investigation on rock dynamics mainly focused on the intact and non-persistent
fractured rocks, rather than the persistent fractured rocks, while understanding the dynamic …

This paper presents an investigation of wave transmission in complex rock masses; the
rocks have different wave impedances on either side of a joint. The conventional …

The blasting response of jointed rock mass under high-stress conditions is studied in a
laboratory experiment using model specimens. The crack initiation mode and initiation angle …
