Near-surface borehole mining waterjet cutting reach-radius test:


Since measurement of a BHM stope requires special equipment and procedures, an easy and quick beforehand jet-cutting test is recommended, similar to the one pictured above. In this case, the tool is located on top of the production interval with its hydromonitor lowered to a short distance below the surface. It typically takes a few minutes for the jet to get through the ore and reach the surface (in this case 26FT). This test provides a quick glimpse of the BHM possible cutting reach-radius - one of the most important parameters of borehole mining.
