Water. Large quantities of water are used in mining operations for cooling machinery, dust suppression, cleaning, firefighting and drinking. Water supplies are normally carried in steel pipes from surface to points close to the work places, with flexible hoses used for the final connections.
The water cannons use high pressure blasting with water to break coal at a rate of 2,000t/day. The crushed coal is then washed downhill through a 10kmlong, low pressure, slurry pipeline to a processing plant. The waterfed coal slurry is partly supported by pump and partly by gravity.

However, ever since the introduction of continuous miners in the late 1940s, roomandpillar continuous mining has been gaining ground over conventional roomandpillar mining.
Safety considerations and the drive to obtain as much coal as possible from an area led to the progressive replacement of underground mining by opencast mines. However, underground mining was also revolutionised in New Zealand by the use of highpressure water jets to extract the coal, which was then transported out of the mine by the water.
