Blasting a Dam - Search Videos

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 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

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

The drill and blast method is a widely used technique in tunnel construction, especially in hard rock environments. This method involves drilling a series of holes into the rock face, filling them with explosives, and then detonating them to break the rock into manageable pieces. After blasting, the debris, known as muck, is removed. Drill and blast is favoured for its effectiveness in excavating through tough geological conditions, but it requires precise planning and control to minimise vibrat
