Is RC drilling hard work?
RC drilling works well in both overburden and soft, broken rock formations but its main strength is when it gets to hard composite rock. It is cost efficient due to the simplicity of the percussive drilling process and because the equipment needed is less complex.
How does RC drilling work?
Reverse Circulation (RC) drilling is one of the three main types of mineral exploration techniques offered by Ranger. Used to compile sample rock cuttings, the drilling process relies on hollow inner tubes to transport samples back to the surface in a continuous flow, using compressed air.
How fast is RC drilling?
RC drilling achieves higher production rates and can achieve up to 200/300 metres per day. This means that results can be delivered to clients faster, as the drilling itself takes less time.
What is the difference between RC and diamond drilling?
Diamond drilling is more efficient for precise sampling and analysis, whereas RC drilling is adept at extracting bulk samples. When it comes to speed, RC drilling is the faster method.
How much do drillers offsiders earn?
Find out what the average Drillers Offsider salary is Entry-level positions start at $70,200 per year, while most experienced workers make up to $93,600 per year.
How long does it take to become a qualified driller?
Some mining companies offer traineeships in drilling operations (level 2 or level 4) or driller (level 3). These take 1-2 years to complete. Traineeships are great because you can earn them while you work.
What is a RC drill rig?
Reverse Circulation drilling, or RC drilling, is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow.
How fast is diamond drilling?
Broken ground is free to move so instead of cutting, the rock is removed by a grinding action. Under these conditions (three body wear), diamond bit wear is extremely rapid and rotational speed should be cut to half RPM and weight on bit sufficient to reach 1 to 2 ipm (3 to 5 cpm).
How deep can a diamond drill go?
A previous diamond drilling record occurred in 2008 when Major Drilling achieved a record-breaking depth of more than 3,400 meters at Red Lake, Ontario, Canada. The new record at Windfall is a testament to Major Drilling’s ongoing efforts to achieve the best possible results for its clients.
What is an RC rig?
What is HQ drilling?
A letter name specifying the dimensions of bits, core barrels, and drill rods in the H-size and Q-group wireline diamond drilling system having a core diameter of 63.5 mm and a hole diameter of 96 mm.
Is drilling a hard job?
Drilling is labour intensive and physically demanding work. But for many FIFO drillers out there, drilling is the perfect job, especially for those looking to save up a nest egg and break into the property market.
What is a FIFO driller salary?

Is it hard to be a driller?
One of the best entry-level roles for someone looking to get into the mining industry is as a Driller’s Offsider. We won’t lie though, it’s a bloody hard job physically, but the rewards are definitely serious.
How does a RC hammer work?
During drilling, compressed air is injected into the annulus of the dual-wall pipes and drives the RC-DTH hammer to implement high-frequency blows acting on a reverse circulation drill bit where the reverse circulation is formed.
What is RC mining?
Reverse Circulation (RC) drilling is a quick drilling method used in mining exploration for evaluating chip samples and gathering preliminary geological data. Generally conducted prior to diamond core drilling programs, it is possible the drill to 500m depths utilizing RC drilling, with typical depths of 100 to 250m.
How much does a driller earn?
“There are even higher rates for those drilling underground, with $65/hr (Diamond) and $75/hr (Production) being offered for some contract roles.” But let’s take a closer look at what it takes to earn that kind of salary as a Driller.
Are diamond drill bits actually diamond?
2. How Are Diamond Drill Bits Made? To manufacture these drill bits, producers use the pressure of up to 1.5 GPa and temperature of about 1250 degrees (Celsius). The makeup of these drill bits consists of real diamond powder, pressed onto the steel using this very high pressure.
