Hydraulic transport of coal has been used for many years on the West Coast of New Zealand to extract small blocks of steeply dipping coal. Recent development at Strongman 2 Mine has seen the use of high pressure monitors to cut coal and a corresponding increase in the scale of production. This paper provides a brief introduction to hydraulic mining, describes the present system used at Strongman 2 and discusses future potential development.
