Jun 23, 1993· Abstract: Recent work on an electrical method for breaking rock shows that such technology is progressing toward commercial applications. The method, called plasma blasting, is based on the fast delivery of stored electrical energy to fracture the rock. In this paper, an overview of the work done during the last eight years at the Noranda Technology Center is presented.
Using a non-explosive product for rock and concrete breaking completely eliminates flyrock, noise, vibration from blasting, human discomfort and structural damage related to air blast overpressure. Compared with conventional concrete and rock breaking methods, Expanding Grout is safe, easy-to-use and cost-effective.
