satisfy plant requirements plays an important role. A mine can be set up in one of two ways; either the plant is set up to accept whatever fragmentation the blasting group produces, or the plant dictates to the mining teams the fragmentation distribution they will accept. To achieve what the plant wants, electronic detonators are required.

Sa2.5 level – is commonly used in industry and can be used as an acceptance technical requirement and standard level. Sa2.5 level is also called near-white cleaning level (near-white or out-white level). The technical standards for Sa2.5 level treatment: the same as the first half of Sa2 requirements, but the defects are limited to …

Blasting caps (including electric) shall not be transported in the same vehicle with other explosives. ( e) Vehicles used for transporting explosives shall be strong enough to carry the load without difficulty, and shall be in good mechanical condition. ( f) When explosives are transported by a vehicle with an open body, a Class II magazine or ...

Excavation schedules and drill bench dimensions will influence blast hole size, explosive selection, and labor requirements. The proximity of blasting to structures can profoundly affect blast planning. Blasting near structures or urban areas adds a special set of additional concerns. The need for pre-blast structure surveys, vibration …

A soda blaster can be used wet or dry. When used wet, the water acts as a dust suppressant and the dust will typically fall in 10-15ft of the work area. However, when blasting dry, containment for the dust is typically required. There are some tips and tricks like dropping 6 mil plastic sheet down in your blasting area.
