煤矿采区智能掘进监控系统的应用

Application of Intelligent Power Supply System for Driving Face

为确保煤矿井下掘进工作面的安全稳定高效运行,分析了智能化矿井的发展进程,发现目前煤矿监控系统并没有掘进系统设备的远程集中控制。为此,根据《煤矿安全规程》对高瓦斯矿井“双电源双风机自动切换”和“三专两闭锁”的要求以及现场的实际需求,设计出了一套基于可编程控制器(PLC)和力控组态软件的智能化掘进监控系统。该系统可以通过上位机对掘进工作面设备集中远程监控,远程监控设备的运行状态、控制设备的分合闸,实现设备与设备的联锁控制等功能。通过搭建模拟实验台进行测试,当瓦斯超限以及发生故障时可以快速动作,满足《煤矿安全规程》要求,并且满足现场实际需求。该系统提高了掘进工作面的自动化程度,对提高掘进系统的可靠性以及掘进工作面的安全高效生产有一定的实践意义。

In order to ensure the safe,stable and efficient operation of underground driving face of coal mine,the development process of intelligent mine was analyzed,and there was no remote centralized control of driving system equipment in the monitoring system of coal mine.Therefore,according to the safety regulations of coal mine,automatic switching of double power supply and double fans and three special and two locking were carried out for high gas mine requirements and the scene of the actual demand,a set of monitoring system of intelligent excavation based on programmable controller(PLC)and force control configuration software was designed.The system could centralize remote monitoring,remote monitoring equipment running status and control equipment of switch,equipment and equipment interlocking control,and other functions through the PC to the tunneling working face equipment.Through building simulation test-bed,when the gas overrun and failure could quickly operate,and met the requirement of coal mine safety regulations and the actual demand at the scene.The system improved the automation degree of heading face.It has certain practical significance to improve the reliability of driving system and the safe and efficient production of heading face.
