Core drilling is the process of making precise circular cuts in concrete to make smooth openings for a variety of applications. Many concrete cutting companies employ state-of-the-art diamond cutting technologies to make their work as precise as possible. A variety of methods are used depending on the application.

Evidence from the air-core drilling is that there has been a degree of remobilisation of metals within the palaeo-water table. This means that the low grades seen in the air-core results are unlikely to reflect fresh in-situ mineralisation grades – which can only be determined by follow-up diamond drilling.
AIRCORE DRILL PROGRAM The high priority follow-up infill AC drilling is comprised of 20 holes totalling 2,200 metres and will be undertaken to improve the definition of the grade distribution at several of the established Ni-Cu-Co-PGE geochemical footprints, with the northern Eyre Anomaly being a priority due to the current lack of drilling.

Sonic Drilling - Sonic drilling is a safe, clean and low-impact drilling technique. Boreholes are drilled, cored and cased by rotating and vibrating the rod, core barrel and casing at resonant sonic frequencies. Sonic drilling generates considerably less drill spoils than auger, mud or air rotary methods, saving additional project resources.

Drilling has confirmed the palaeovalley is at least ...
Air rotary drilling is sometimes referred to as RAB or Rotary Air Blast drilling, which further confuses people. RAB is similar in its function to rotary air, with a spinning drilling bit forcing its way through an ore to then blow the materials back to the surface. RAB drilling goes to lower depths, to approximately 25m and is mostly used for ...

Aug 28, 2019· Air core drilling is an inexpensive method of exploration drilling that can be employed when safe removal of sample material is paramount. Where possible, it is preferred over RAB (Percussion rotary air blast drilling) drilling and unlike the diamond drilling method, which withdraws a small diameter core of rock from the orebody, air core drilling is much faster and more cost-effective.
A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface.Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers.Drilling rigs can sample subsurface mineral deposits, test rock ...
During 2009, aircore and diamond drilling were conducted to primarily target the discovery of new VMS deposits on the Salt Creek tenement (E47/1088), as well as the further delineation of the Balla-Balla mineralisation. Work was undertaken to drill the East Balla prospect with encouraging results, and to further constrain the volcaniclastic sedimentary horizon across the Salt Creek tenement.
Bulletin Resources Limited (ASX:BNR) has finalised its latest aircore drilling programme at the Lake Rebecca gold project, 150km east north-east of Kalgoorlie, Western Australia. The Lake Rebecca gold project is immediately along strike of Apollo Consolidated Limited's 1.1M oz Rebecca Gold Project.

Sep 12, 2006· Percussion drilling is the manual drilling technique that was used in the first well drilled in North America. In this drilling technique, a hammering bit is attached to a long cable that is then lowered into a wide open hole. As such, it is also called cable drilling, wherein the driller uses a tripod to support the tools.
Aircore drilling uses bladed bits to drill unconsolidated and semi-consolidated Formations such as weathered regolith (loose, heterogeneous material covering solid rock). The airflow utilized in this method of drilling is similar to reverse circulation however the drill bit only utilized rotational motion in the case of aircore drilling.
Air-Core Drilling uses steel or tungsten blades to bore a hole into unconsolidated ground.The drill cuttings are removed by the injection of compressed air into the hole. This method of drilling is used to drill the weathered regolith (loose, heterogeneous material covering solid rock) as the drill rig and steel or tungsten blades cannot penetrate fresh rock.
