Covering blasting with blasting mats or soil helps control fly rock and air overpressure by containing the energy and debris generated during the blast. Blasting mats absorb and disperse the shockwave, reducing the likelihood of fly rock projectiles being ejected from the blast site. Additionally, soil cover acts as a barrier, absorbing energy and preventing the propagation of air overpressure waves beyond the blast area, thereby minimizing the impact on surrounding structures and environments.

The drill and blast method is a widely used technique in mining operations, particularly in hard rock mining. This process involves two key components: drilling holes into the rock formation and subsequently blasting the rock to facilitate its fragmentation. Drill patterns are meticulously designed to optimise the blasting process, considering factors like rock type, size, and desired fragmentation. The drilling phase utilises specialised equipment to bore holes into the rock, where explosives a

Drill and blast method is one of the common tunnelling techniques in hard rock. The principle behind the blasting in tunnel is to create a free face at the centre of the tunnel by means of cut holes and then extending the blasting to the full face of tunnel. In simple words, blasting relies on two main factors: 1. shock wave to create cracks in the rock 2. Expansion of gas to move into the cracks to crush the rock. In our online Tunnel Engineering course, you will learn blasting techniques in tu
