Sandvik has launched a new automatic injection system aimed at improving the safety, precision and efficiency of resin-based ground support in underground operations.
The HPA20 automatic injection pump is designed for use in hard-rock mining and civil engineering applications, enabling both manual and fully automated injection of two-component silicate and polyurethane resins.
The system can operate as a stand-alone unit or be integrated with underground equipment, offering flexibility across a range of ground support tasks including rock bolting, anchoring and ground consolidation.
Sandvik said the HPA20 is particularly suited to operations using drill rigs that cannot accommodate onboard bulk resin systems.
In automatic mode, the HPA20 records detailed data from each injection cycle, including mixing ratios, pressures and pumped volumes. This information can be exported and integrated into site quality assurance and control systems, supporting increasing requirements for traceability in ground support processes.
According to Sandvik, the system’s compact footprint and multiple transport options allow for easier deployment in underground environments, with an optional hydraulic power pack available for sites requiring additional capacity.
Sandvik product manager ground support Anssi Kouhia said the HPA20 provides a flexible alternative to manual injection methods, combining automation, monitoring and safety features in a single platform.
