井下跳汰排矸及矸石回填控制系统的设计

Design of Control System of Underground Jigging and Gangue-backfilling

针对现有地面选煤及排矸方式存在的费用高、土地占用面积大、污染严重等问题,提出一种井下跳汰排矸及矸石回填控制系统的设计方案,介绍了该系统的硬件组成、通信方式、控制流程及软件设计。该系统的上位机采用iFIX组态软件对现场设备进行实时监控;下位机以S7-300PLC为核心,采用STEP7编程软件实现跳汰控制、选煤排矸、煤泥水处理及安全应急处理功能;系统人机交互功能由MT8000触摸屏实现。该系统在邢东煤矿的应用在国内首次实现了井下跳汰排矸选煤,系统运行过程中未出现任何故障,效果良好。

In order to solve problems of high cost, large occupied area and serious pollution, the paper proposed a design scheme of control system of underground jugging and gangue-backfilling, and introduced hardware constitution, communication mode, control process and software design of the system. In the system, upper computer uses iFIX configuration software to real-timely monitor and control field devices, lower computer uses $7-300 PLC and STEP7 software to realize functions of jigging control, gangue, coal cleaning, processing of sl computer Mine for interaction ime water and emergency treatment, and MT8000 touch screen realizes human e system realized underground jigging and gangue-backfilling in Xingdong Coal the first time in the whole country and got a perfect effect without any fault in running
