Carbomine, a phenolic injection resin, was first developed for the Australian coal market to stabilise underground rock formations. The resin is fully LOBA compliant and meets strict safety and environmental standards.

Carbomine has low viscosity to penetrate the fines cracks, low exothermic temperature and high bond strength to ensure geological stability. The two component system is mixed at a 4:1 ratio, which makes it ideal in combination with Minova’s cavity fill product, Carbofill, as the same pumping equipment can be used. The dual use of the same application pump ensures substantial time saving in set up for applications where both products are found advantageous to meet safety and production requirement.

Carbomine has a very low exothermic temperature of less than 60 °C and during in underground field trials, neither phenol nor formaldehyde was detected. The excellent strata penetration and superior bond strength characteristics make Carbomine an ideal choice for underground application.

Carbomine has recently had a very successful Australian underground application at Donaldson Coal’s Tasman Mine near Newcastle. Carbomine was injected into a rib line as a precautionary sealing measure to prevent spontaneous combustion after air passages through the coal pillar had found elevated heat. The application was successfully completed by experienced personnel from Minova’s NSW Operations and Technology teams.
