Overview
The KT15i intelligent surface DTH drilling rig is designed for blasting-hole drilling in open-pit mines, stone quarries and engineering construction. RTK positioning, drilling assistance and automatic drilling functions support intelligent mine operations, with a drilling-data system and network-dependent remote control.
Key highlights
- ✓RTK-based positioning with an error of less than 10 cm as stated in the brochure.
- ✓Imported drilling-coordinate files guide automatic feed-beam positioning and drilling-angle adjustment.
- ✓Automatic drilling adjusts opening and drilling parameters to the rock structure, with anti-sticking control and automatic drilling, lifting and rod handling to the preset depth.
- ✓Automatic drilling-data collection and transmission, with measurement-while-drilling and lithology acquisition systems.
- ✓Where mine network conditions permit, a control room can remotely operate multiple machines; remote control is mainly used for tramming.
Applications: Blasting-hole drilling in open-pit mining. · Stone-quarry blasting-hole drilling. · Blasting-hole drilling for engineering construction projects.

Recommended packages
Air compressor match
Integrated rig — the screw air compressor is built into the machine, so no separate compressor unit is needed. Only confirm the onboard compressor rating (pressure and flow) matches your hammer size.
DTH hammer & bits
Match the DTH hammer class to your hole diameter: K3/K30C for 90-105 mm, K5/K50 for 135-165 mm — see the DTH hammer series page for the full ladder.
