Diverter Valves Optimize Backfill Operations
Underground mines use intricate piping networks, known as backfill systems, to fill stopes after extracting ore for processing. There are three types of backfill commonly used in conventional mining operations cemented paste (CPB), hydraulic and dry tailings. A backfill system generally consists of a main pipeline dropping vertically 656 ft (200 meters [ml) or more below the surface, where it levels out horizontally and the flow can be split into two different pipelines. This piping structure may repeat at each level of the mine, depending on the project. Some projects may require repeating this process at every level of the mine. Al- though the need for line repositioning varies depending upon site conditions and mine standards, generally the manual changeover process happens frequently. The company shut down its 6-in. (150-millimeter [mm]) feedline and flushed it with water to remove any tailings and paste backfill that built up during the filling process.
