Blasting is the technology use in breaking rock mass or boulders into specified require sizes by the use of Explosive.
The main objective of Blasting is to reduce rock/Mineral size so as to minimize cost of comminution and other downstream processes.
Poor fragmentation affect other Mining operations like; loading, Haulage, crushing, and separation process.
It also increase production cost and operation cost. Most Quarry and mine practice secondary Blasting or implement hydraulic breaker to further reduce Blasting output.
It therefore good to subscribe to better blast design to ensure good blast output result so as to avoid further reduction expenses.
What is micro fracture?
Fractures are crack or breakage in rock mass.
Micro fractures are the cracks create in rock mass by Explosion shock waves during Explosive charge detonation.
What is the important of micro fracture in rock fragmentation?
The micro fracture creates slabbing in rock mass and through this cause the failure of the rock and Explosion after high pressure gas fill up the fractures.
How can we increase micro fracture in rock during Blasting?
