The exploitation of underground mineral deposits is dominantly accomplished using drilling and blasting. The large-scale blasting with higher explosive consumption is practiced to achieve the production targets. However, such large-scale blasting induces ground...

the volume of rock. Further, the tendency to specify "ultra-safe" vibration limits for blasting, results in unnecessarily slow and expensive progress. Th e problems arising from the above trends can largely be avoided by applying appropriate blasting expertise well ahead of the commencement of blasting operations, excluding inappro-

Blasting is a process of reduction of rocks or hard soil into fragments with the help of explosives. The blasting operation involves drilling of holes, installation of a detonator and charge, detonating the charge, and removal of debris. ...

It covers the economics of the entire rock blasting operation and its dependence on the size of excavation. The book highlights the fundamentals of rock mechanics, shock waves and detonation, initiation and mechanics of rock motion. It describes the engineering design principles and computational techniques for many separate mining methods and ...

Blasting constitutes a crucial aspect of mining and construction activities, influencing both productivity and safety. The process of blasting in mining and construction operations demands meticulous attention to various factors including rock type, blast area dimensions, and the selection of explosives (Yang et al., 2019, Qiu et al., 2018).In recent years, there has been …

permits the use of explosives specific to the following blasting operations. These are classified as follows: A Class A (AboveBelow Ground) Certificate or Class B (Aboveground) Certificate is …

By implementing these measures, mining and quarrying operations can substantially improve safety and minimize the impact of flyrock incidents. INTRODUCTION. …

This book is a unique supplement to contemporary scientific literature on rock blasting technology. It encapsulates theoretical and practical aspects of drilling and blasting techniques used in both surface and subterranean excavations connected with civil as well as mining activities. Case studies are presented to illustrate correlations between theoretical calculations and empirical …

The book also covers the recent advancements in methodologies to predict blasting outcomes and instrumentations for monitoring rock blasting operations. The book is a useful reference for rock blasting practitioners, …

Additionally, factors such as in-situ stress conditions, rock temperature, and the presence of any pre-existing damage or alteration zones can also influence the behavior of the rock mass during blasting operations [7, 11, 12]. Prediction of the optimum fragmentation size will help the mining industry in selecting blasting parameters to produce ...

About this four-part series. In 1963, Pit & Quarry published a series of articles on the mechanics of blasting authored by Richard Ash, a longtime professor of mining engineering at the School of Mines & Metallurgy …

Furthermore, it is still unclear how much stemming affects rock cracking and rock fragmentation in blasting operations (Zhang 2016 (Zhang, 2019. Therefore, it is necessary to investigate rock ...

Measuring the blast-induced ground vibration at blasting sites is very important, to plan and avoid adverse effects of blasting in terms of the peak particle velocity (PPV). However, the measurement of PPV often requires time, cost, and logistic commitment, which may not be economical for small-scale mining operations. This has prompted the development of …

Blasting activities in mining and quarrying operations play a pivotal role in extracting valuable resources from the Earth's crust. However, a significant risk associated with blasting is the occurrence of flyrock.

At Precision Blasting Services, we understand the crucial role that rock blasting plays in the construction, mining, and civil engineering industries. Our team of highly skilled professionals is dedicated to offering the most advanced and …

However, in this study, a two-dimensional analytical modeling of the rock blasting operations has been accomplished considering the elastodynamics principles and fundamental solutions using the Green's functions. Therefore, a Green's function has been derived in terms of displacements. Then, the strain and stress fields related to this ...

Blasting operation is widely used method for rock excavation in mining and civil works. Ground vibration and air-overpressure (AOp) are two of the most detrimental effects induced by blasting.
