摘　　要：目前我国大部分煤矿井下排水系统依旧采用传统的人工排水方式,应急性差、保护措施落后,存在很大的安全隐患。针对这些问题,基于PLC控制技术,共设计主水泵、副水泵、检修水泵3台水泵,以水仓内水位的监测数据作为控制水泵的基本条件,实现3台水泵的自动控制运行,同时加入报警系统和电路保护系统,以增强系统可靠性,达到自动控制系统稳定、安全、高效运行的目的,满足矿井排水的系统要求。At present,most of the underground drainage systems of coal mines in China still use the traditional artificial drainage methods,which have poor emergency response and backward protection measures,and there are great potential safety hazards.In response to these problems,based on the PLC control technology,a total of 3 water pumps,the main water pump,the auxiliary water pump and the maintenance water pump,are designed.Taking the monitoring data of the water level in the water tank as the basic condition for controlling the water pump,the automatic control operation of 3 water pumps is realized.At the same time,alarm system and circuit protection system are added to enhance the reliability of the system,to achieve the purpose of stable,safe and efficient operation of the automatic control system,and to meet the system requirements of mine drainage.
