According to frequent pressure regulation, pressure regulation delay and the pressure regulation low accuracy and other problems existed in the manual pressure balancing,a mine automatic controlled pressure balance fire prevention and control system was designed.According to the site actual conditions,a site certain layout plan of the system was provided.According to the principle and features of the pressure balance fire prevention and control technology, and the relationship between the two end pressure variation and the air leakage value in the pressure balance zone, a pressure regulation redundancy of the automatic controlled pressure balance fire prevention and control system was determined.Based on the Force Control 6.0 configuration software as the development platform,a monitoring and control software of the automatic controlled pressure balance fire prevention and control system was developed. The network parameters of substation PLC were allocated, the initialized substation was applied to simulate the input/output module and the controlled program of the automatic adjusted window was prepared and translated.Thus the monitoring and control of the site equipment operation status could be implemented. The fluid numerical simulation software was applied to simulate the air pressure distribution variation status of the pressure balance area in the goaf and to analyze the advantages of the pressure balance fire prevention and control method.The research and development of the automatic pressure balance fire prevention and control system would be favorable to the coal mining under the fire zone, the opening of the fire zone and prevention coal spontaneous combustion in the goaf.%针对手动均压中存在的频繁调压、调压滞后与调压精度低等问题,设计了矿井自动均压防灭火系统.针对现场实际情况,提出系统现场具体布置方案,根据均压防灭火技术原理、特点与均压区域两端压力变化和漏风量的关系,确定自动均压防灭火系统的调压冗余度.以力控6.0组态软件为开发平台,开发了自动均压防灭火系统监控软件；配置分站PLC网络参数,初始化分站模拟输入/输出模块,编译自动调节风窗控制程序,实现对现场设备运行状态的监测与控制.利用流体数值模拟软件,模拟了采空区均压区域气压分布变化状态,并分析自动均压防灭火方法的优越性,自动均压防灭火系统的应用在火区下采煤、火区启封与预防采空区煤炭自燃方面具有重要意义.
