Since 2001, the Hybrid Stress Blast Model (HSBM) project members have developed a software suite to model the complete blasting process from non-ideal detonation to muck pile formation. To preserve the physics and improve solution time, the breakage engine ...

<p>This document specifies the procedure that shall be followed when a Contractor or Permittee is proposing to blast. By following this procedure, the Engineer-In-Charge or the Permit Engineer can help ensure that the Contractor accomplishes the work in a ...

This paper presents part of the work on ground vibrations induced by blasting, and to estimate safe maximum charge per delay to protect the nearby structures.

The purpose of this study is to measure the size distribution of blasted rock using the digital image processing software “SplitDesktop system” in order to evaluate the efficiency of blasting operation. Site of study is a limestone quarry producing limestone ...

The QuickShot system combines pre-programmed electronic detonators with special on-bench components that enable the user to quickly and easily design the firing sequence solely by using the order of connections. This precludes the user from having to deal ...

It is anticipated that the work presented in this thesis will contribute towards the understanding of the mechanical behaviour of the blast Ȭinduced damaged zone around underground excavations in hard rock masses.

This paper presents results of a project undertaken to monitor, review and optimize the trim blasting and pre-splitting processes at Orapa Diamond Mine in Botswana. The project was specifically incepted to improve the final wall conditions, which continued ...

The aim of this paper is to introduce a robust methodology for the analytical calculation of strains in flexible buried pipelines due to surface point-source blasts.

A 3D multi-parameter model has application for any major mining venture that requires a detailed understanding of the variability in rock mass conditions. These models give engineers a tool whereby they can assess the spatial variability of the rock mass information ...

The United States Department of Health, Education, and Welfare's National Institute for Occupational Safety and Health (NIOSH) is responsible for conducting research and developing educational and training materials in the field of occupational safety and ...
