Hello, everyone.

This is Enta.

We're using drill bits to drill holes, right?

This is what it looks like when it's brand new.

This is a standard ring bit.

I want to use this for as long as possible, but I also want to drill the hole as quickly as possible.

 

That's why we tend to drill with a fair amount of pressure. (Since we're charged per meter.)

The tip is made of tungsten.

It is more than twice as hard as iron and offers excellent wear and impact resistance.

 

But the thing is, since it's made of stone (rock), it gets chipped or broken really easily, you know?

This is it.

While I was drilling, I thought, “Huh? It’s suddenly not making any progress,” and this is what happened...

It's terrible.

If this continues, it will look like the bit at the back.

If you keep spinning this without realizing it, you'll end up completely bald lol

Because we are drilling with a double-pipe system, it is difficult to clearly determine that the ring bit is no longer present, since the inner bit has already done some of the drilling.

 

Different mountains have different characteristics, so the drilling methods vary.

Generally speaking, if you’re drilling an anchor into that hill, you can get a pretty good sense of its characteristics by drilling just two or three holes.

Until then, I imagine there will be all sorts of issues, like getting stuck or getting bitten by a mountain and being unable to get out.

 

Since we're working out of sight, drilling operators rely on pressure gauges and a certain degree of intuition to do their jobs, and

It would be great if there were mountains where you could just show up at the site and start digging right away, but there are surprisingly few mountains like that, aren't there?

Mountains over 30 meters high are especially challenging, and for the first one or two, we’re still feeling our way to figure out how to drill quickly and efficiently.

That's where the pressure of surgery comes from.

If we don't drill and finish the holes quickly, we won't make any money.

Neither ring bits nor casing are cheap, so I'm always on edge, lol.

I suppose that kind of pressure is part of what makes drilling operations so exciting.

 

I think that, just like in the slope stabilization business, other industries have their own unique appeal as well.

Can you all clearly put into words what makes that profession interesting and enjoyable?

It’s a job I tend to just go through the motions with, but I think there’s always that one moment when it really clicks.

Let's put it into words.

It'll be even more fun! Just tell everyone around you!!!

 

See you later.
