That’s to say, we usually use core barrel in very strong rock formations with compressive strength above 100Mpa.

Core barrel can be divided into four types: Core barrel with pin teeth for reinforced concrete; Core barrel with replaceable blocks for strong rock up to 100Mpa; Core barrel with bullet teeth for strong rock up to 100Mpa or rock with deep cracks.
