and the time of detonation of the base charge of the detonator.

Where hole B requires hole A to have fired to provide the necessary relief then hole B is dependent on Hole A.

A term applied to any explosive which can be reliably initiated in the unconfined state by a number 8 detonator.

A length of detonating cord or signal tube by which a Primer is lowered into a blast hole and which is the means of conducting the initiating signal down the blast hole.

A blast hole containing two priming units, usually placed one near the top and one near the bottom of the blast hole.

Where, on a vertical drill pattern, a half spaced angled row is drilled to provide energy into the toe area of the front row.
