【摘要】：张家峁煤矿为设计能力1000万吨/年的大型现代化矿井,原煤生产运输系统装机总容量为4190KW,运输距离4900米,运煤系统主要包括5条胶带,启动需经过人工沟通,且胶带运行、控制方式一直采用逆煤流启动,顺煤流停车的控制方式,使得运输系统存在启动时间长、皮带空载运转、生产效率低下等现象。为此原有系统不能满足自动化矿井建设的要求,课题提出的矿井原煤运输集控系统将运输环节和生产过程中各类参数进行集中控制和监测管理,从而提高系统的可靠性,减少操作人员的误操作,提升煤矿生产效率。运输集散系统通过对现场生产情况与系统功能需求分析,从而确定课题整体方案,完成对胶带运输系统的控制和保护功能。系统以PLC为主控制器,通过工业以太网结合上位机形成集中监控系统,完成对现场各类设备的操作和各类参数信息的采集,如温度、煤灰、堆煤、各类设备运行状态的监测等,为现场故障排除提供实时的信息反馈。系统选用AB系列PLC,总共设立6个PLC站点,搭建以工业以太网为基础的数据交换平台,实现上位机和各站点PLC之间的数据交换。依此为基础,软件环节设计顺煤流一键启停控制逻辑,针对实际情况,设计故障保护停车,故障停车后再启动等逻辑控制,实现故障信息共享和设备之间的联锁控制。建立以组态画面为上位机界面的操作系统,实现系统的集成化操作。在项目实施以后,胶带系统启动时间缩减为30分钟,节省了10%的矿用电能,操作人员和现场故障率也大大缩减,有效的提高了原煤运输效率,达到了预期目的。
[Abstract]:Zhangjiaomao Coal Mine is a large-scale modern mine with a design capacity of 10 million tons per year. The total capacity of the raw coal production and transportation system is 4190KW, and the transportation distance is 4900 meters. The coal transportation system mainly consists of five strips of tape, and the start-up requires manual communication and belt operation. The control mode of reverse coal flow starting and coal flow stopping has been used all the time, which makes the transportation system have many phenomena, such as long start-up time, no-load operation of belt, low production efficiency and so on. For this reason, the original system can not meet the requirements of automatic mine construction. The centralized control system of mine raw coal transportation system is put forward in this paper. The centralized control and monitoring of all kinds of parameters in the transportation link and production process can improve the reliability of the system. Reduce the misoperation of operators and improve the efficiency of coal mine production. By analyzing the field production situation and the system function requirement, the transportation distribution system determines the overall project of the subject and completes the control and protection function of the belt transportation system. The system takes PLC as the main controller and forms a centralized monitoring system through industrial Ethernet combined with the host computer to complete the operation of all kinds of equipment on the spot and the collection of all kinds of parameter information, such as temperature, coal ash, coal heap, operation state of all kinds of equipment, etc. Provide real-time feedback for troubleshooting. The system selects AB series PLC, to set up 6 PLC stations altogether, builds the data exchange platform based on the industrial Ethernet, realizes the data exchange between the host computer and each station PLC. On the basis of this, the software link designs the logic of starting and stopping the coal flow by one key. According to the actual situation, the logic control of fault protection and stopping, starting after the fault stop is designed to realize the sharing of fault information and the interlocking control between equipments. The operating system with configuration screen as the upper computer interface is established to realize the integrated operation of the system. After the implementation of the project, the belt system startup time is reduced to 30 minutes, saving 10% of mine electric energy, the operator and site failure rate is also greatly reduced, the efficiency of coal transportation has been effectively improved, and the expected purpose has been achieved.
