Jetcrete Shotcreting Technologies for the Mining Industry

Jetcrete is a specialist contractor and supplier of underground shotcrete and fibrecrete ground support for mining sites across Australia.

State-of-the-art shotcrete technologies for mining operations

Jetcrete provides standard and remote control shotcrete application, tele-remote controlled shaft lining systems and equipment, and comprehensive ground support solutions such as excavations, bolting, meshing, doweling, steel fixing and formwork.

All shotcrete operators are trained to national competency standards including concrete batching and delivery and shotcrete application. Select operators are also assessed to European Federation of National Associations Representing for Concrete (EFNARC) standard by its own EFNARC examiners.

The company uses modern techniques and placement materials to maintain optimal operations and a safe working environment, without disrupting ongoing mining works.

Innovative shotcreting engineering

Jetcrete has created modern technologies such as overhead wet shotcrete, robotic shotcrete units and hydro-scaling.

These have resulted in improved early strength support, increased development rates through faster excavation cycles, and enhanced bonding between the fibrecrete and the substrate surface.

Jetcrete has collaborated with major suppliers to develop specialised mixes and tested advanced technologies to meet industry requirements. In addition, the company is consistently involved in the research and development of new solutions and industry guidelines.

Tele-remote shaft lining systems

Jetcrete’s remote shaft lining system comprises three cameras and three lights for inspecting the shaft, a hydraulic motor to drive the rotation of the nozzle and water dosing protection.

The rig is fitted with Mines Department Approved enclosures and lighting, making it suitable for mining operations.

Monitoring equipment, dry shotcrete and hydraulic packs are deployed away from the shaft collar. Handrails and barricades with signage are appropriately set-up before the application of shotcrete begins. The shotcrete application is monitored and recorded using CCTV.

Regular mining equipment and process audits

All Jetcrete sites are developed with an inspection test plan (ITP) to regulate the testing requirements that satisfy specifications of the client, Jetcrete and Australian Standards.

The company’s site testing procedures include:

• Casting batch plant cylinders and beams
• Spraying of in-situ and round determinate panels
• Regular testing of aggregates and cement compliance
• Testing site water
• Calibration of batch plant scales and dosing units

All testing is performed by National Association of Testing Authorities (NATA) accredited independent test laboratories throughout Australia.

In addition to the ITP, the company regularly audits all equipment and processes for optimal quality.
