露天矿煤棚属于半封闭空间,生产作业时处于重度污染状态,严重影响工人身体健康。针对露天煤矿筛分栈桥煤棚的特殊环境,综合运用传感器技术、PLC控制技术,设计了一套智能通风降尘系统,实现对煤棚内粉尘浓度的实时监测和智能控制。系统根据采集到的粉尘数据按照Fluent数值模拟获得的控制策略自动调整通风设备的运行状态,优化通风设备的工作效率,从而精准降低粉尘浓度,改善作业环境。实验结果表明,开风机后PM2.5较未开风机前降低了61.11%,PM10降低了35.04%。该智能通风降尘系统能够有效降低煤棚内的粉尘浓度,改善工人的作业环境,同时降低能耗,具有良好的经济效益和社会效益。

The open pit coal shed belongs to a semi enclosed space that is at heavily polluted status during production operations, seriously affecting the health of workers. In response to the special environment of screening trestle coal shed in open-pit coal mine, an intelligent dust reduction system is designed by comperhensively adopting sensor technology and PLC control technology to achieve real-time monitoring and in-telligent control of dust concentration inside the coal shed. The system automatically adjusts the operating status of the ventilation equipment according to the collected dust data and the control strategy obtained through Fluent numerical simulation, optimizing the working efficiency of the ventilation equipment, thereby achieving precise reduction of dust concentration and improving the operation environment. The experimental re-sults show that after turning on the draught fan, PM2.5 decreases by 61.11% and PM10 decreases by 35.04% compared to before turning on the draught fan. This intelligent dust reduction system can effectively reduce the dust concentration inside the coal shed, improve the working environment for workers, and reduce energy consumption at the same time, with good economic benefits and social benefits.
