The SAC system is an integrated equipment combining electronic technology, computer control technology and hydraulic technology to achieve multi-functional, high-efficiency and automated control of hydraulic supports. The system is capable to realize: Individual support control; Group control; Automated follow-up control with shearer; Personnel detection; Lockout & emergency stop functions; Fault display and alarm; Automatic pressure compensation; Pressure-holding support moving.

The system optimally meets the automation requirements of fully-mechanized coal mining faces. By adopting electro-hydraulic control, it significantly: Increases support movement speed (30-50% faster than manual operation); Enhances automation level (enabling unmanned face operation); Reduces manual labor (60% fewer operators required); Improves efficiency (20-35% productivity increase); Strengthens safety features (real-time monitoring and emergency protocols).
