An intelligent fluid supply system with pressure self-adjustment is proposed for comprehensive mining face,and its pressure characteristics are simulated using the electromechanical-hydraulic joint simulation platform.Field tests and industrial applications show that the intelligent fluid supply system for the hydraulic support of the comprehensive mining face is able to reduce the pressure pulsation of the hydraulic support,the amplitude of the flow impact decreases,and intelligent control of the leakage amount is realised,which effectively improves the quality of the fluid supply to the hydraulic support of the comprehensive mining face,and verifies that the design of the system has improved the quality of the hydraulic support and has improved the quality of the hydraulic support.The quality of hydraulic bracket fluid supply in the comprehensive mining face verifies the reasonableness of the programme design.In addition,the conclusion of the study provides reference for the later optimisation of the hydraulic system to achieve multi-machine synergy.
