Part 36 Mining

Section 676 Shock blasting

Subsection 676(1)

Shock blasting is generally used to relieve stresses and pressures developing for geotechnical reasons or because of gases trapped behind the face. Once stresses are released, the surrounding formations become more stable and easier to support with some degree of predictable behaviour.

A Director may allow shock blasting if the conditions of subsection 676(2) are met. An application for shock blasting must be submitted by the employer.

Subsection 676(2)

A professional engineer must prepare the procedures for performing shock blasting to ensure that related safety issues are adequately addressed.
