The hole story: the benefits of drill and blast

2016-4-21  Changes in drillhole placement and blast timing can be performed before the drilling operator drills the holes. This approach allows for design changes before a single hole is drilled. If a high-precision guidance solution, such as Leica J2drill, is used to drill the holes, as-drilled data can feed into blasting simulators to adjust the blast design further before a shot is fired.

Petropedia - What is Blasthole Drilling? - Definition

RAB (Rotary Air Blast) drilling is used frequently for Blasthole Drilling. In this type of drilling methodology, a piston driven hammer generally pneumatic reciprocating type drives heavy drill bit into the rock with a lot of force. The drill bit is a hollow solid steel material with approximately 20mm thick tungsten rods which hold the drill bits.

Drillability Prediction in Rotary Blast Hole Drilling

Rotary blast hole drills were observed in fourteen rock types at eight open pit mines. The net penetration rates of the drills were calculated from the performance measurements. Rock samples were collected from the drilling locations and the physical and mechanical properties of the rocks were determined both in the field and in the laboratory. Then, the penetration rates were correlated with ...
