Features of Fully Hydraulic Core Drilling Machine for Mining

1. Optimized overall structure

• Integrated tower and machine, enabling quick hole layout and relocation, greatly saving manpower and material resources.
• Crawler chassis with manual + remote control mode, safe and convenient.
• Mast telescopic drill frame structure, no need for a drill tower, fast to carry and disassemble, with high safety.
• Top-drive power head with long-stroke guide rail, cylinder propulsion, no need for repeated rod reversing, good guidance and directionality.
• Small machine footprint, no foundation engineering required, green and environmentally friendly.

2. Full hydraulic transmission

• Flexible layout, lightweight, easy to operate, and simple maintenance.
• Stepless speed regulation, can run at high speed, stable drilling process, and low vibration.
• Real-time grasp of downhole conditions through various pressures, with pressure limiting protection, high safety.

3. Adaptable drilling technology

• The drill string system can ensure “full, rigid, straight”, which is conducive to hole deviation control.
• Combined with thin-walled drill bits, it can achieve low torque resistance, fast cutting speed, and high drilling efficiency.
• Can ensure large core diameter and high core recovery rate.
• Due to the equipment structure design, the annular gap is well controlled, which is not easy to cause block falling and sticking, with few accidents and high safety.

Working Process of Hydraulic Core Drilling Machine

• Preparation work: First, level the ground; use the equipment’s own system to find level; adjust the mast angle according to design requirements; dig a mud pit, connect the mud pump, and other preparation work.

• Start drilling and lower casing: Just like building a building needs to lay a good foundation, drilling construction needs to lower the casing in advance, and the specific requirement is that the casing goes into the bedrock. The reason for lowering the casing: the surface overburden is generally soft, and in the later drilling process, there will be slag falling and collapse, which directly affects the smooth progress of drilling. The stable crawler chassis of the equipment is conducive to casing lowering operations.

• Official drilling: Hoist and connect the double-pipe drilling tool assembly to the power head, start the mud pump, and officially start drilling. Each drill pipe is 1.5 meters long. After drilling one drill pipe, the power shackle rises, and then connect another 1.5-meter drill pipe, and repeat this cycle.

• Grab the inner pipe and take out the core: After completing the round trip footage, the core in the inner pipe is full. At this time, it is necessary to use a hydraulic winch to lower the fishing tool into the drill pipe with a steel wire rope. The fishing tool falls freely to the inner pipe under the action of gravity, then fish out the inner pipe, and then take out the core from the inner pipe.
