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

Charging, blasting and ventilation of a rock tunnel using drilling and blasting method is schematically and briefly shown in this short video. Charging can be done manually or mechanically depending on the explosive type. Drilling and blasting pattern should be designed in advance and adjusted based on the real condition of the rock regularly. #drillandblast #drillingandblasting #blasting #blastingengineer #tunnelling #tunneling #tunnelengineer #hardrocktunnels #rockmechanics #rockengineering #t

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
