How does underground core drilling machine work?

Underground diamond drilling aims to effectively delineate and sample underground mineral resources at various scales and stages whilst providing advanced information from which mine designs and excavation strategies can be developed. Diamond drilling (DD) aims to test multiple domains within the established mineral resource at wide and close-spacings.

Full Hydraulic Underground Drill Rig is mainly used for the drilling of gas drainage holes, hydrological exploration and other engineering holes. This system adopts full hydraulic transmission, coaxial double pump drive, stable transmission, simple speed adjustment, and can be configured with multiple linkage modes, with strong process adaptability and simple operation. The mechanical structure design is reasonable and compact, the action is reliable, and it is convenient to disassemble, connect and move. The drilling rig is arranged in groups, and the whole machine is composed of three parts: the main engine, the pumping station and the operation table. The hose connection between each part can flexibly arrange the relative positions of the three, with good disintegration, and convenient for relocation and transportation. In areas with poor transportation conditions, the host can be further dismantled.

1. The full hydraulic underground drilling rig is split-type layout. This, along with its light weight, makes its transportation effortless, its operation flexible.

2. The feeding and rotation function of the unit head is accomplished like this: the explosion-proof motor and control system of the power unit puts the hydraulic pump in motion. Thus, the hydraulic fluid comes into being. By means of the hydraulic fluid, the motor makes the spindle rotate and multi-speed mechanism of the hydro-cylinder chain work.

3. The hydraulic chuck can accomplish the clamp and breaking out of the drilling rod as well as the function of block-out prevention.

4. The mast slide itself. The underground diamond core rig can also stretch out and draw back. This maintains a close touch between the mast and the foundation. As a result, the underground drilling rig will have an enhance stability.

5. The up-and-down swing of both the mast and the swing frame ensures the drilling from multi angles.

6. The spindle of the unit head has a wide range of rotary speed, thus a large rotary torque.

As a kind of underground diamond core rig, it is used to the large-diameter gas drainage and the water injection hole of mine, tunnel and coal mine. It is also used to the large-diameter horizontal drilling of the surface engineering. The full hydraulic underground drilling rig can accomplish the large-diameter cone drilling, large-diameter hard-metal drilling and the percussive-rotary drilling.

Modular drill rigs designed to reduce downtime. Each underground drill is equipped with modular rigs and mobile platforms, making our equipment easy to use and move from site to site.
