SUMMARY OR ABSTRACT
Text of Note
Mine waste rock is often recycled for paste and cement backfill in underground cut and fill mining operations. Aggregate in concrete and road surfacing material is another use if the mine waste does not contain deleterious materials that can degrade surface and ground water quality where it is used. Shotcrete usage in mining has been primarily limited to packaged dry mixes from offsite manufacturers. Substituting a manufacturer's pre-mixed shotcrete with crushed and sized mine waste rock can reduce both the shotcrete cost and the environmental impact of waste disposal operations by reducing the required volume capacity and footprint size required for a disposal facility for the waste material.
