Abstract

Based on the full monitoring of mine ventilation system by a safety surveillance control system, the feedback control is applied to design a hierarchical control model. It mean that the total mine air volume is controlled by a main fan power supply module converter, the roadway area is controlled by an electric ventilation door, and the air volume of workplaces is controlled by the air register installed at the end of compressed air duct. The control of whole ventilation system is implemented using intelligent modular design. Through the communication interface, the parameters of the air speed and pressure of each laneway and air point for the ventilation system are collected, and the environmental safety status parameter is also considered, to adjust the effective air volume in production, and to optimize the structure and air volume of the ventilation system in the changing conditions of environmental security. The control strategy is divided into a dynamic adjustment scheme for the production safety state, and a manual-intervened adjustment program in the conditions of prediction deviation of safety state with the change of environment security. Through the ventilation data provided by the adjustment scheme, the intelligent module controls the ventilator, the electric ventilation door and the wind regulator in the outlet of air-supply duct to achieve the effect of both major and fine adjustment. Thus, the air quantity is always maintained in the range of safe level.
