Part 36 Mining

Section 659 Permitted explosives

Subsection 659(1)

Permitted explosives are designed specifically for use in coal mines where flammable gases may be present. These explosives are subjected to extensive testing by the Chief Inspector of Explosives, Natural Resources Canada.

Subsection 659(2)

The use of non-permitted explosives is allowed provided they meet other requirements of this section and the Director is satisfied with the safety measures certified by a professional engineer. Rock in which these explosives will be used must not contain flammable hydrocarbon gases or coal. Many limestone formations lie near coal beds and carry flammable gases within them. The employer and the professional engineer must assess each formation before submitting an application to the Director.

Subsection 659(3)

The employer is responsible for ensuring that mine workers are appropriately trained and that controls are in place to ensure that workers do not take unapproved explosives into an underground coal mine.
