Expandable hoses for the coal industry

In the development of mine shafts, there is a problem of reducing the strength of the rock and preventing dust formation. Our company has developed and proposed a solution to this issue – the use of elastic expanding sleeves. They are used as sealing elements for sealing boreholes or boreholes in the coal industry.
The sleeves are used for pumping liquid and are efficient at ambient temperatures from minus 35 to plus 45C in mine water with a solid content of up to 100 mg / l, at a water pH of 6.0 to 9.6 and temperatures from plus 5 to plus 45C.
Today Rubex Group is the exclusive manufacturer of elastic expanding sleeves in Russia. Many mines in Ukraine and Russia are successfully using Rubex Group developments to ensure uninterrupted operation and safety in the field of underground mining.
