Read More2016-4-21 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.

The use of blasthole drilling data is advantageous since it is acquired systematically, routinely, and in real time .In the mining industry, monitoring while drilling (MWD) is a standard practice for obtaining penetration rate (PR), rotational speed, flushing pressure, and GPS-based drillhole ...
Read More2017-8-24 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

Read More2020-7-14 Drilling is a way of standardising pronunciation of a language item and developing fluidity (the ability to introduce language quickly and easily). The idea is for learners to develop good pronunciation habits by first listening to a model from the teacher, and then repeating this model several times while receiving positive and negative feedback for their efforts.

Read More2020-4-8 At the Drill and Blast Summit in Brisbane in April, BHP’s mine automation readiness engineer, Jack Chaston, said autonomous drilling led to increased machine utilization and consumable life. He said the autonomous PV271s were 16% faster per hole, had 20% additional utilization and one-third extra drill
Read MoreRotary 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 ...
Read MoreDrilling system solution for optimum blast holes in minings and road construction job sites. Get better quality control through improved drilling accuracy of both positioning and depth. Less need for stakes, construction surveying, and personnel near the machine during drilling operations. The grade control system improves rock fragmentation in your quarries and civil engineering projects.

Read MoreDrilling Machine: It is a machine which is used to drill the holes on the components or workpiece with the help of drill bits. The drill bits are also called as Multi-point cutting tools which can have their rapid impact on the Material Removal Rate (MRR) i.e. a single-point cutting tool (like the one used in a lathe machine) can remove the material slowly whereas, a multi-point cutting tool ...

Read MoreRAB (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.

Alternatively, reduce the torque if you want to drill more slowly. You should also make sure you're taking regular breaks if you're drilling through hard material so the drill bit can cool down.
