TAURO MineStar – Coal Mining Hose

400 bar

TAURO MineStar 400bar NR/SBR TAURO MineStar 400bar NR/SBR

In underground coal mining industry high pressure water injection helps to eliminate methane-gas and soften the stone wall. The water injection hose is placed into a hole drilled in the wall and under 400 bar pressure expands such a way that it completely seals the hole. After operation the hose returns into it’s normal state. In typical length of: 1500, 2500, 5000, 6000mm, other length up to 20m is possible.
