This video described the whole process of charging and blasting in opencast mining. Procedure: A drill jumbo during the construction of Citybanan under Stockholm, used for drilling holes for explosives As the name suggests, drilling and blasting works as follows: *A number of holes are drilled into the rock, which are then filled with explosives. *Detonating the explosive causes the rock to collapse. *Rubble is removed and the new tunnel surface is reinforced. *Repeating these steps until the desired excavation is complete. The positions and depths of the holes (and the amount of explosive each hole receives) are determined by a carefully constructed pattern, which, together with the correct timing of the individual explosions, will guarantee that the tunnel will have an approximately circular cross-section. During operation, blasting mats may be used to contain the blast, suppress dust and noise, for fly rock prevention, and sometimes to direct the blast. #miningblastingvideos #Mining #Coalmining Tags: drilling and blasting in mining, Drilling, Blasting, Mining, Opencast Mining, blasting mining, underground mining blasting, drilling and blasting in underground mining, blasting process in mining, open cast mining blasting, mining blasting videos mining blasting, mining blasting videos, mining drilling and blasting, open cast mining blasting, underground mining blasting, blasting materials for mining, plasma blasting mining, stone mining blasting, blasting open pit mining, mining blasting pattern, blasting in mining operations, surface mining blasting, solid blasting mining technical, open cast mining blasting videos, underground mining blasting videos, mining blasting video download, mining blasting methods, strip mining blasting, mining blasting materials, limestone mining blasting, mining blasting certificate training, underground coal mining blasting, mining blasting caps, mining blasting barricades, mining blasting videos status, mining blasting compilation, opencast coal mining blasting, open cast mining blasting method, gold mining blasting, underground mining blasting in hindi, mining blasting status, blasting explosives for mining, mining blasting whatsapp status, mining blasting process
