Since 2001, Minova has invested technology and resources into developing the correct methodology and optimal product design to consolidate (previously unconsolidated) material to form artificial rockfill pillars.
FB200 was developed as a low viscosity, flowable, high yield cement grout with complete void penetration, easy pumpability and dimensional stability. FB200 is ideal for optimised ore recovery as the grout offers unique rapid gel times, quick strength, low viscosity and high water content, allowing for controlled placement through carefully designed borehole patterns to gain maximum penetration of the unconsolidated rockfill.
