Graduated in geography a couple of years ago, but now developed an a sudden yet strong attraction towards geology and it’s mining related work (due to comprehending not just the economic good of the work, but as a moral good). So stubbing upon your videos will no doubt help in pursing field work related jobs and / or postgraduate study. Your explanations are good for the layman. So thanks for your continued work and I hope I’ll be able to come work in Australia in the near future.

Awesome video, I love the RC rig. It was all a mystery to me how it actually worked all I know is those rods are heavy as buggery if you are manual handling them because the support truck cant move close enough to the rod handler. That being said after I watched your video I was shocked by the max depth you mentioned and asked some driller I'd worked with last night what the max depth was and how deep he had gone. He replied 800m and I said how do you get any return and he said "more air". Their drill rig with offboard booster can drill over twice your max depth according to him but we'd had a few.
@GeologyUpSkill
@GeologyUpSkill 2 жыл бұрын
It is possible to drill deeper, but it's a game of diminishing returns because you drill slower, it costs more and the risk of getting stuck goes up. Beyond about 400m, diamond core is equal or better.

i worked as an offsider in my 20s, we used to run rods maunally , that is swing them in to position using the weight of the rod. .hard to explain to people who dont know what im talking about. Man what a rush..sure looks tame today. Pajingo, charter towers, kajabi, tarcoola , mundi mundi plains. all for exploration , so camping with the rig...miss those days and the friends i made

Interesting video, right now I'm having an issue with rc drilling, I'm working in a limestone formation with clay, and the hammer doesn't work well with soft formations and with high moisture. Now we have changed the bit to a tricone bit adapted to rc drilling to deal with high moisture and soft formations.
@GeologyUpSkill
@GeologyUpSkill 3 жыл бұрын
Limestone is a challenge for all types of drilling because it tends to form large cavities that can divert huge amounts of drilling fluid or air. They can be difficult or impossible to seal with regular cementing methods.

Ive done offsiding for these drills underground except our rig was on tracks ive had to do 100 metre rod pulls multiple times with bits sometimes 2ft or bigger in diameter. Ive been in waist high water changing rods and under there we also drilled upwards so everything is falling on you while theyre drilling. The rods because theyre wet and oily are even harder to handle then they would be when dry sometimes its just easier doing it with no gloves. Ive had to jump over holes that are 100 metres deep 2ft wide in diameter doing that 80 times on separate occasions in 1 shift while holding the rods. The rods we used were aroind 1.8metres tall but looked much heavier then the ones theyre using in this video Let me tell you right now they do not pay enough youd get maybe 450 a shift which is around the same amount a guy sitting on his ass in a truck gets, people new to the industry dont know that because no one tells them. Trust me 350 to 450 a shift is not enough to do that shit Unless ofcorse you have a rod handler which is a mechanical arm that does all the hard work

Really nice video. But what's the different between Positive circulation drilling and RC drilling?
@GeologyUpSkill
@GeologyUpSkill 3 жыл бұрын
Open hole or "positive" circulation drill rods are a single hollow tube. Air is pumped down inside the tube and returns up the hole outside the rods. Reverse circulation drill rods have an inner and outer tube. Air is pumped down between the outer and inner tube then returns up inside the inner tube. The animation in the video shows the different air paths with moving arrows.

Looking at using an RC rig here in the states for uranium, but am unsure if it will work. We will be drilling 800-900 feet in shale, swelling clay, and sandstone and will have artesian flow at surface. We typically use regular mud rotary rigs and weight up with barite to supress the artesian flow, but there is a huge rig shortage where I am and am desperate to get any rig at this point. Will an RC rig be able to handle the sticky clay/shale and the artesian flow? Thank you for the great videos!
@GeologyUpSkill
@GeologyUpSkill Жыл бұрын
That artesian flow will be a problem. You can keep it out with lots of air while you are drilling, but it will fill up the hole each time you stop to put on another rod.

How deep can an rc drill rig dig
@GeologyUpSkill
@GeologyUpSkill 2 жыл бұрын
That depends on many things (volume and pressure of the air supply are the biggest factors), but holes beyond 400m get pretty slow and difficult so RC has much less advantage over diamond at that depth.

In truly exceptional conditions that is possible, but the rate of progress goes down and the likelihood of a hole failure goes up with every metre beyond 400. As a result, the real world costs approach those of diamond core and the speed advantage is lost.
