A remote control system of a hydraulic bracket for an unattended working face of a coal mine mainly comprises the structure that the hydraulic bracket on the working face is remotely controlled via a ground host and a central control room host, an intelligent analysis and early warning strategy is made for an operating state of the underground hydraulic bracket by the ground host, automatic following and pulling control of the hydraulic bracket is conducted by an end controller, and three-stage network monitoring and controlling of the ground host and the central control room host, the central control room host and the end controller as well as the end controller and an inter-frame controller in an electrohydraulic control system is achieved by a multilayer communication system of the electrohydraulic control system of the hydraulic bracket. The system employs PowerBuilder as a front end development platform, achieves electrohydraulic remote control of the hydraulic bracket on the unattended working face of the coal mine, can be connected with any database and is very high in applicability.
