I. What is Wire-line Coring and Drilling?

Wireline core drilling is a special type of core drilling, most commonly used for minerals exploration. Unlike some types of drilling, the aim of core drilling is not to make a hole, but to retrieve a core sample- a long solid cylinder of rock that geologists can analyse to determine the composition of rock under the ground.

II. Advantages of Wire-line coring

1. Saving both Time and Labour

No need to take every piece of the drill strings out to get the sampls,saving a lot of time to hoist and disassemble the drill rods.

With wireline drilling, a barrel of core can be removed from the bottom of the hole without removing the drill rod

string assembly.

In this process most of time is available for drilling and so speedier progress can be made with the same time spent

in actual drilling.

2. Get larger core samples

For wireline drilling, the rods are made of fine hightensile steel. This makes them thin, so that the core can be as large

as possible.

3. Making deep exploration available

Wire line drilling is possible up to a depth of 1000m,or far more than that.
