Deliver grout and chemical products from the surface to underground. Depending on the product our delivery system can deliver grout based products from the surface to underground via a borehole or portal, taking around 15 minutes to fill a pumpable crib. Chemicals can be pumped using a variety of pumping methods and can be pumped up to 3,000 m from the surface.
Our surface to seam solutions include:
• Reduce chemical exposure and manual handling of chemicals
• Reduces the need for "exclusion zones"
• Maximise safety, increase efficiency and minimise labour footprint
• Pumping from the service can eliminate up to 95% of underground activity
• Easy to set-up and relocate
• Install ventilation seals and pumpable cribs using the same equipment
Minova have successfully completed a range of surface to seam applications:
• Pumpable cribs installed in under 15 mins
• Complete ventilation plug seal (from the surface) in 4-6 hours. Rated 120psi, pumped 160m deep down a borehole and 700m horizontally to complete 6 bulkheads
We are the original developers of the technology for dual component long distance pumping, grouting and liquid cement systems.
Minova's Pumpable Crib system has been developed to provide enhanced standing and roof support in underground coal mining. Typically installed for gateroad secondary support, Pumpable Cribs are a cost effective alternative to tin cans or timber cribs. Our system provides a more productive means to install standing support in longwall mining operations, reducing exposure for operational personnel and more cost effective mine production.
Using our patented Tekpak® P technology, we allow you the flexibility to install Pumpable Cribs from the one surface location. A surface to seam operation allows mines to reduce equipment and material movements underground along with reduced operators underground.
We have invested in full scale testing of our Pumpable Crib's at an Australian NATA accredited facility, giving our customers confidence that our Pumpable Crib technology will perform to Australian conditions.
We have installed ventilation seals throughout Australian coal mines for more than 15 years. We offer full roadway evaluation, seal design and contract installation of explosion rated seals. Our installed structures are fully rated and quality control tested to ensure construction is completed according to design specifications.
Working with a NSW coal mine we developed an approved design and using FB200 installed a plug seal rated to 120 psi. The FB200 was pumped 160m deep down a borehole and 700m horizontally to complete six bulkheads.
Our team have more than 20 years’ experience of design and installation (including live and engineered designs) in Australia. We have developed an extensive database of ventilation designs for even the most challenging applications.
Only contractor to have completed live explosion testing of ventilation seal designs.
Pump injection chemicals up to 3,000m from the surface using a variety of pumping methods. Pumping chemicals from the surface eliminates up to 95% of activity. This means less exposure to chemicals and reduced manual handling. Limit the transportation of materials underground and reduce manning levels.
Minova pioneered the first resin, application systems and design formulations into Australian mines based on German technology.
