Controlled Blasting Controlled blasting techniques are used to efficiently distribute explosive charges in a rock mass, thereby minimizing the fracturing of rock beyond the crestline of the highwall or designed boundary of main excavation areas. Such over-fracturing, commonly called overbreak, is typically more of a problem in soft or unconsolidated, incompetent overburden formations. There are several techniques that a blaster can use to minimize overbreak, but trials should be conducted to det

Blasting mats as important component of blasting are used to control fly rock. These mats, typically made of materials like rubber, effectively absorb and disperse the energy generated during explosions, minimising the potential for rocks and debris to be propelled beyond the blasting zone. In addition to fly rock control, blasting mats help contain air overpressure, and facilitate a safer working environment, underlining their integral role in responsible and efficient blasting practices.
