Blast Dynamics, Inc. | Training Courses

Controlled Blasting for Rock Slopes

This course focuses on the development, implementation and refinement of wall
control blast designs.

Included in the topics to be covered will be:

Basic slope design considerations

Geological factors that influence slope stability

Defining various “zones of stability” within your pit

Rock damage mechanisms

The influence of blast vibration on wall stability

Wall control techniques including modified production, trim and presplit blasting-air decking and line drilling

Drill and explosive selection

Developing specific design approaches for each “zone of stability”

Quantifying blast performance with the use of borehole cameras, vibration monitors, video cameras and other advanced technology

Refining the blast design to achieve optimum results
