Apr 01, 2021Blasthole drilling is one of the most important operations from a cost and its influence on the performance of the crusher, mill and concentrator post blasting. Good drilling accuracy enables efficient controlled blasting operations. Different blasting techniques are used in underground mining.
ContactBlast hole drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, for the purposes of packing it with explosives and detonation. The intention is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.

ContactAug 24, 2017What is Blast Hole Drilling? Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.

ContactAug 24, 2017Blast hole drilling is traditionally used wherever the mining company wants to explore the mineral composition or potential mineral yield of the area demarcated for their mining interests. Blast holes are thus a fundamental step in the exploratory mining process, and can be employed in both surface mining operations and underground mining

ContactBlasting tunnels (or drifts) is a necessity in all underground mining operations. Drill and blast techniques are the most conventional and common method and is most useful in high UCS and homogeneous rock types albeit slower than other methods. These tunnels are created for many reasons including: Using the excavated space for transport
