- Hydraulic boom
- Feed beam
- Rock drill (drifter)
- Control panel
- Articulated chassis
- Four-wheel drive system
- Drill string
Working Principle
The Kaishan KS313i underground mining drilling rig operates on a hydraulic drilling system combined with a diesel engine for tramming. The engine powers the hydraulic pumps, which supply pressurized oil to the boom, feed, and rotation circuits. The operator positions the boom and feed beam using the control panel, then activates the drifter (rock drill) to apply impact, rotation, and feed force to the drill string. For rotary drilling, the rig uses a rotary head to turn the drill pipe, while for DTH drilling, a down-the-hole hammer is attached to the drill string and activated by compressed air from an onboard compressor or external source. The cuttings are flushed out of the hole by air or water. The rig's articulated chassis and four-wheel drive allow it to navigate tight underground tunnels, while the low-profile design ensures stability and safety. The hydraulic system provides smooth and precise control, enabling accurate hole positioning and efficient drilling in various rock conditions.
