A blasting in tunnel. Drill and blast method is one of the most flexible tunnelling methods in hard rock. This method can be performed in wide variety of geological condition, in any tunnel shape and dimension. Design of the drill and blast pattern is an important part of this method. Ground borne vibration, air blast and fly rock are important factors that should be considered in the design along with more common parameters such as advance rate, powder factor, drill factor, maximum instantaneou

The drill and blast method is a widely employed 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 explosiv

The drill and blast method is a widely employed technique in mining for extracting valuable minerals. It involves a sequential process where specialised drilling equipment is used to bore holes into the rock, strategically positioned to maximise mineral recovery. Following drilling, explosives are inserted into these holes and carefully detonated to fragment the rock into manageable pieces. This controlled fragmentation facilitates easier extraction and transportation of the ore. The drill and b

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
