Wireline Double Core Barrel For Borehole Drilling Machine
A wireline core barrel is a tool used in geological and mining exploration to extract core samples from the earth. It consists of a cylindrical barrel with a cutting bit on the bottom that is lowered into the ground and rotated to cut a cylindrical core sample. The core is then lifted to the surface by a wireline, which is a thin cable that can be easily raised and lowered. The wireline core barrel is often used in situations where it is important to retrieve a continuous sample of the subsurface, such as in mineral exploration, oil and gas drilling, and geotechnical investigations.
