Prediction of ground vibration induced by blasting operations through the use of the Bayesian Network and random forest models

Soil Dynamics and Earthquake Engineering, 2020
The present study aims to compare the performance of two machine learning techniques that can unveil the relationship between the input and target variables and predict the ground vibration (peak particle velocity, PPV) due to quarry blasting.

Blast injuries

The Lancet, 2009
Health-care providers are increasingly faced with the possibility of needing to care for people injured in explosions, but can often, however, feel undertrained for the unique aspects of the patient's presentation and management. Although most blast-related injuries (eg, fragmentation injuries from improvised explosive devices and standard military ...

Blast Injuries

The Journal of Emergency Medicine, 2015
Blast injuries in the United States and worldwide are not uncommon. Partially due to the increasing frequency of both domestic and international terrorist bombing attacks, it is prudent for all emergency physicians to be knowledgeable about blasts and the spectrum of associated injuries.Our aim was to describe blast physiology, types of blast injuries ...

Rock damage control for large-diameter-hole lateral blasting excavation based on charge structure optimization

, 2020
Controlling rock damage induced by lateral blasting excavation is a source of concern. In underground mines, large-diameter-hole lateral blasting excavation often causes engineering disasters such as large blocks falling and overall collapse of the ...

Blast-Furnace Melting Blast Control

2019 IEEE Russian Workshop on Power Engineering and Automation of Metallurgy Industry: Research & Practice (PEAMI), 2019
The paper suggests an approach to the blast-furnace melting control for improving the blast furnace process efficiency. The approach is based on the simulation of the blast furnace operation and online stabilization of parameters based on the obtained mathematical models.

Optimization of spherical cartridge blasting mode in one-step raise excavation using pre-split blasting

, 2020
In one-step raise excavation, spherical cartridge blasting mode is easy to be implemented due to minimal requirement of the hole-deviation. Nevertheless, it may induce cumulative damage to the country rock. This study firstly uses a validated rock model (
