KT integrated open-air DTH drill rig
KT15i Intelligent Open-pit Down-the-Hole (DTH) Drill Rig (Open-pit Rock Drilling Robot)

introduction and Parameter:

Open-pit mines, rock works, engineering construction

Precise vehicle positioning Adopting RTK survey technology, it accurately locates drilling positions with positioning error less than 10cm, exceeding standard requirements for open-pit blasting.

Drilling auxiliary system Automatically adjusts feed beam position and drilling angle via imported borehole coordinate files to meet mine construction standards.

Automatic drilling system Supports automatic drilling mode. It adjusts drilling parameters adaptively according to rock formation, realizing efficient rock drilling and anti-jamming drilling. It automatically completes drilling, rod lifting and rod handling until reaching designed depth.

Data processing system Automatically collects and transmits drilling data to build process database. Equipped with measurement-while-drilling and real-time lithology acquisition functions.

Remote control system Connects to central control room under stable network for remote operation. Single operator can manage multiple units. It enables remote driving control and reduces on-site staff.

Note: Due to continuous technological updates and advancements, any discrepancies between technical parameters, configurations and actual products shall be subject to the delivered goods. Besides, the equipment shown in pictures may include optional accessories.
