One of the world’s largest copper producers has chosen Sandvik to deliver 16 Sandvik D25KX down-the-hole (DTH) rotary drill rigs for its operation in Zambia. A DTH rotary drill rig is a type of drilling equipment that uses compressed air to drive a hammer at the bottom of the hole, enabling efficient rock penetration and allowing for faster, deeper drilling in tough ground conditions. The addition of these advanced drill rigs is expected to increase drilling speed by 20%, reduce maintenance downtime, and support safer operations in challenging terrain. Moreover, the new Sandvik D25KX rigs are designed to optimize fuel efficiency and reduce emissions, supporting the mine’s commitment to sustainable operations.
The order, placed in 2025, includes Sandvik’s Remote Monitoring Service, specialised training, and 12 months of technical support with spare parts stock to ensure high uptime and enhanced drilling productivity. Remote Monitoring Service allows for real-time equipment performance tracking, helping operators resolve issues quickly and minimise disruptions. All 16 drill rigs will be supplied in sequenced batches throughout 2026.
The new fleet of 16 DTH Sandvik surface drills will supplement the mine’s ageing group of nine Sandvik D25KS and four Pantera™ DP1500i drill rigs, which have been in operation since 2016. Integrating these state-of-the-art rigs will help meet increased production targets, improve operational efficiency, and support the mine’s recent expansion efforts—including a new processing plant, upgraded smelter, and a new open pit designed to boost annual throughput.
Sandvik D25KX is a diesel-powered, crawler-mounted DTH rotary drill rig, engineered for hole diameters between 127–203 millimetres (5–8 inches) and capable of reaching depths up to 27 metres (88 feet). Key features include a high-pressure air compressor system for improved drilling performance, heavy-duty pulldown chains for durability, a mast designed for rugged mining terrain, and a modern operator cabin with electro-hydraulic controls and large windows to enhance visibility and safety. These features contribute to more reliable, efficient, and safer drilling operations while supporting the mine’s sustainability goals.
