Hydraulic hoses for coal‑mine hydraulic supports play a critical role in underground mining operations, with their working principle relying on the coordinated interaction between hydraulic transmission and the support system. This paper outlines the operating principles of these hoses and highlights their significance in mine production.

Hydraulic hoses for coal‑mine hydraulic supports are an indispensable component of the support system. Their operating principle is based primarily on hydraulic transmission: pressure is transmitted through a closed pipeline system, enabling the support to raise, lower, and stabilize. The hoses are filled with hydraulic oil; by controlling the pump station, oil is pumped into the hose, generating high internal pressure that drives the support cylinder’s piston to perform lifting and lowering motions.
In coal‑mine production, by regulating the hydraulic oil pressure inside the hoses, the support’s height can be precisely controlled, ensuring safe working conditions for underground miners. Moreover, hydraulic support hoses exhibit high‑pressure resistance, corrosion resistance, and wear resistance, enabling reliable operation even in harsh mine environments.
Hydraulic support hoses used in coal mines play critical roles in bearing loads, providing structural support, and ensuring worker safety. Proper application of their operating principles not only enhances mining productivity but also safeguards miners’ well-being. Consequently, during equipment maintenance, the inspection and upkeep of hydraulic support hoses are of paramount importance to ensure the reliable operation of the support system and the continuous flow of mine production.
