This core drilling machine for mining combines high torque, stability and good core integrity rate, and is suitable for a wide range of complex geological environments such as metal mines, non-metallic mines, coalfields and geothermal.
Features of Core Drilling Machine for Mining
Compared with ordinary core drilling machine, YG’s hydraulic core drilling machine has many advantages in mining applications.
- The hydraulic drive system ensures a smooth drilling process and reduces the probability of core breakage and core loss.
- The machine also supports a variety of drill bits, such as diamond bits and PDC bits, which can easily penetrate hard rock and broken zones. This kind of design makes core drilling machine for mining not only suitable for census, but also for detailed investigation tasks.
In our experience, customers often choose hydraulic rig machines over traditional mechanically driven drilling rigs because of the better handling stability and reduced operational risks associated with hydraulics.
Typical Applications of Core Drilling Machine for Mining
- Geological exploration of metal deposits;
- Detailed investigation of non-metallic minerals (e.g. graphite, quartz);
- Geothermal resources development pre-drilling;
- Coal seam geological investigation and gas anomaly identification.
For customers who are interested in purchasing core drill rig for sale, this kind of multifunctional model is the preferred choice to improve drilling efficiency and reduce comprehensive cost.
What Is Rope Coring? Why Are Hydraulic Core Drill Rigs Better?
Wireline Coring allows the operator to extract the core without pulling out the drill pipe, which is extremely important in holes deeper than 300m. The precise control of the hydraulic system makes hydraulic core drilling rigs the perfect vehicle for this technology. Mechanical or wind driven drilling rigs cannot achieve the same efficiency, which is why customers purchasing hydraulic borewell machines often choose the hydraulic type.
Use tips and operation precautions
- Reasonably control the propulsion force to avoid excessive pressure leading to core breakage.
- Drill bit selection should be adjusted according to the geological properties of the formation, such as diamond drill bit for hard rock and PDC drill bit for soft rock.
- Make sure to disconnect the power and stop the operation of the hydraulic system when lifting and lowering the drill pipe to prevent the personal risk caused by misoperation.
- Clean the rope channel in time after each drilling to keep it free.
- If there is a risk of collapsing the ground, it is recommended to install a wall protection pipe.
