Background

Core drilling is the most commonly used method for geological exploration work, is used for mastering the physical properties of rock masses, and is used for drilling on site by using a core drilling machine, and the taken core pillar is the first data in the mining process, so that a large amount of analysis and experimental research can be carried out.

Especially, the core taking work in a coal mine tunnel is difficult, the tunnel core taking adopts the traditional core taking drill rod to be connected with the drill rod connecting end of a drilling machine, the drill rod is disassembled when the core taking of the core taking drill rod is finished, and the core in the core taking drill rod is taken out. The method is widely used due to the simple structure and single operation of the coring drill rod, but the core in the coring drill rod cannot be completely and quickly taken out when the core is found in the actual operation process, and workers usually force the core removal work of the coring drill rod by adopting water pipe pressurization and strong physical vibration, so that a large amount of working time is wasted, and the coring drill rod is damaged to a certain extent.

In the core removing process from the core taking drill rod, a small amount of rock is broken and stays in the core taking drill rod in the drilling process, so that rock slag is clamped in the rock core and the inner wall of the drill rod, the drill clamping phenomenon is caused, and the rock core cannot be taken out in a short time. In the normal coring process, the core is cored due to strong physical vibration, secondary damage is carried out on the core, the core is broken, and the core cannot become an experimental material. The comparatively broken of rock core can make the workman can't judge the concrete order of putting of rock core to lead to the lithology judgement mistake of rock core post.
