Southern Kuzbass Coal Company Launches Output of High-Pressure Hose for Use in Mines

Southern Kuzbass Coal Company (part of Mechel Group) acquired a facility for testing high-pressure hose used in hydraulic equipment. The new acquisition cost over three million rubles.

High-pressure hose are used in hydraulic excavators, bulldozers, boring machines and heavy-duty trucks as flexible conduit for oils, fuel, gases and emulsions. 

A specialized department at Southern Kuzbass Coal Company has been producing pressure hose for equipment used at the company’s open pits since 2018. Now, thanks to the option of testing them at the new facility, the company will be able to use the hose underground as well, at powered supports, mining and tunneling machines.

The hose are tested for tightness, possible deformation and other specifics under pressure that is nearly double the maximum operating pressure. A special module records the data received during testing. The facility is intended to work with pressure of 150 to 1,300 bar, is equipped with sensory control and a system of quick installment for the tested product.

“Our V.I. Lenina Underground Mine’s new longface will require some 9,000 high-pressure hose, and this time they will be produced by us, not bought from third-party suppliers. We are sure of our product’s reliability. Besides, Southern Kuzbass Coal Company supplies Korshunov Mining Plant (another Mechel company) with high-pressure hose for use on PC-3000 and PC-4000 excavators,” Southern Kuzbass Coal Company’s Managing Director Igor Ritikov said.
