Abstract
The authors developed a pilot project to test different preparations of cemented rock fill, determine the appropriate mix design, and check necessary mix strength. The article presents the required resistance studies and the research method used to determine feasibility, cost performance and increased mine productivity and safety. The study achieved a resistance peak of 1.6 MPa, reduced dilution of the ore, and increased pillar stability.
