Rock Blasting Fundamentals

Daniel A. Vellone, M.S., P.G.

Controlled rock blasting methods have been used to excavate rock in shafts, tunnels, and chambers at many projects at urban locations throughout the United States. Rock Blasting consists of drilling holes in a rock mass at depths, in diameters, and at spacing so that an explosive can fracture the rock in a controlled manner to break ore, rock or to create space.

This course provides engineers and geologists with an introduction to rock blasting fundamentals including practical blast design techniques, a basic presentation of explosives and their characteristics, explosive selection criteria, risk management practices, initiators and timing effects as well as patterns are also discussed. Blast-induced ground vibrations and airblasts are discussed along with methods for monitoring, evaluation and control.

This course is intended for geo-professionals (geologists or engineers specializing in geotechnical or geological engineering) concerned with the design or engineering review of controlled blasting programs. Additionally, this course may be beneficial to municipal engineers and professionals in construction management responsible for the hiring of specialty contractors to perform blasting operations.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
