Part 36 Mining

Section 631 General duties

A blaster is appointed by the employer and assigned authority to control the blasting area. In taking charge of the area, the blaster must be prepared to direct and control the activities of everyone involved for the period required to complete the blast. The general duties of the blaster are described in subsections 631(1) through 631(6).

Depending on the complexity and size of the blasting operation, a blasting engineer may be involved in designing the loading, firing sequence and delay sequence used in the blast. Similarly, a blast involving a few hundred thousand kilograms of explosives will require a group of people to ensure that the job is done correctly. Loading of explosives, once drilling is complete, may itself take a few days or weeks to complete.
