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 in mining and tunnelling involves the use of explosives to break rock and excavate materials. In mining, blasting is primarily used to fragment rock to extract valuable minerals, often requiring precise control to maximise ore recovery while minimising dilution and damage to the surrounding rock. In tunnelling, the primary objective of blasting is to create underground passages and spaces, necessitating careful design to ensure stability and safety of the tunnel structure. While both ap

Blasting is a highly skilled process that, when properly designed and executed, can be safely used for rock excavation even in sensitive areas such as around residential buildings. By employing controlled blasting techniques, blasting operations can minimise ground vibration and air overpressure and ensure the safety of nearby structures. The use of blasting mats further enhances control by effectively containing fly rock. With careful planning and expert execution, blasting becomes a versatile
