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.

Blasting techniques in rock tunnels involve strategically drilling a series of holes into the rock face, which are then filled with explosives. These explosives are detonated in a carefully planned sequence to maximise rock fragmentation and control the shape and size of the tunnel. The flexibility of the drill and blast method in rock tunnels is one of its greatest advantages. It allows for adaptation to varying geological conditions, accommodating changes in rock type, hardness, and structural

The drill and blast method in tunnelling involves drilling a series of holes in a precise pattern, then filling them with explosives to break and remove rock. The design of the drill and blast pattern is crucial, as it determines the effectiveness and safety of the operation. It factors in rock type, tunnel size, and desired fragmentation. Proper sequencing and timing of blasts are essential to minimise vibration, control overbreak, and maintain the tunnel's structural integrity. Follow us at tu

How to control rock fragmentation? In order to control fragmentation, two important principles must be correctly applied. The proper amount of energy must be applied at strategic locations within the rock mass. The energy must also be released at a precise time to allow the proper interactions to occur.
