BEST PRACTICES IN DRILL AND BLAST
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.

The Ultimate Guide to Abrasive Blasting | SafetyCulture
Abrasive blasting is when a high-pressure stream of air or water removes paint, rust, or other debris from a surface. It can be used on metal and non-metal surfaces and is often used to prepare surfaces for painting or other forms of finishing. This process is also sometimes used to clean graffiti from buildings or other structures.
