Ah yes, my mistake lol

Lucky for Bro, you'd be scarred for life! :eek:

The world's deepest cave system only extends about a mile downwards. The Taratoga gold mines of South Africa could take you close to the 2-mile mark, but your best bet is to start tunnelling from the Mariana Trench. This is the deepest ocean trench, plunging 7 miles (11km) down under the Pacific Ocean.

Howdy RESiNATE,

Okay,I understand now,what you were talking about..tha's mighty deep,for a mine . Whereas,I was talking about drilling depth,with the typical hole in the Austin Chalk,in South Texas,being around 10,200ft -11,100ft max..5286 ft,is one mile. It generally took us about 5 hours to round-trip a drill-bit at that depth..the heat from the earth at that depth,made the drill-pipe and drill-collars,nice and warm in the winter-and miserably hot and steamy-any other time..lol.

Have a good one...Torog

Ah lol

So how is the drill bit made?
Is it in sections?
Like, one section would be (for example) 100ft long, then you'd bolt on further sections to gain the depth?
I would imagine that the amount of torque stresses exerted on the joints, would have been phenomenal!

Interesting, Torog.
:)

Howdy Res,

Actually,the drill bit is just that , a component in and of it's self..it's less than two feet long,and usually consists of three rotating cones,that mesh together and are tipped with hardened teeth or diamond-tipped teeth. Drilling mud is pumped down the pipe and comes out in three jets that both cut and clean ,the bit and hole. The bit is attached to the collars,which are in sections around 30 feet or so,they serve as weights that help the drilling string,to drill straighter. We did use heavy-duty drill pipe,each section,about 30 feet long,and pulled em out in 90 foot sections,three drill pipes at a time..that's what we call a triple drilling-rig,there are also doubles and singles. The entire assembly of drill-bit,collars and drill-pipe,is called the drill string. The typical weight of a 2 mile string,is around 682,000 lbs..and up. There are deep-well earth rigs that are rated up to a 1,750,000 lbs..they can drill down to 38,000 feet or more.

Have a good one...Torog

Ah, thanks for that Torog...you learn something new everyday lol:D

Thats some high numbers there! :eek:

I wonder if one drilled far enough down, whether you could make yer own Volcanoes lmaooo!
Did you ever get any drill strings snap?
Heck, imagine the tap n die set required to get the bugger back out :eek:
