Application
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
