摘　　要：针对庙沟铁矿露天转地下开采过程中主要生产系统智能化建设需要,从无人化和本质安全角度出发,对该矿集控中心、中央水泵房、空压机站及电机车驾驶系统开展了智能化建设研究。通过建立管控一体化调度指挥集控中心和数据网络中心,可以对各个排水设备及空压机站进行远程控制与监控。通过对现有8台电机车进行改造,实现电机车现场手动操控及地面远程遥控功能;同时,采用无线WIFI基站结合光缆传输完成运输巷道的无线覆盖,缩短网络切换时间到毫秒级别,安全可靠且技术成熟;信集闭系统在调度站还配有工控机及显示器,对列车运行情况实时监控,对于道岔处、装矿点、卸矿点等列车运行困难地段实时视频监控;电机车障碍物检测系统检测到有障碍物后立即发出安全预警,同时控制机车降速或制动。系统智能化建成后,设备操作人员可减少23人,总体经济效益为207万元,实现了庙沟铁矿露天转地下开采本质安全化。研究成果可为类似条件矿山智能化建设提供指导与借鉴。In response to the need for intelligent construction of the main production system during the open-pit to underground mining process at Miaogou Iron Mine,research was conducted on the intelligent construction of the mine's centralized control center,central water pump room,air compressor station,and electric locomotive driving system from the perspectives of unmanned and intrinsic safety.By establishing an integrated control and scheduling command center and data network center,remote control and monitoring of various drainage equipment and air compressor stations can be achieved.By renovating the existing 8 electric locomotives,the on-site manual control and ground remote control functions of the electric locomotives can be achieved.At the same time,wireless WIFI base stations combined with optical cable transmission are used to achieve wireless coverage of transportation tunnels,reducing network switching time to milliseconds,ensuring safety,reliability,and mature technology.The information gathering and closing system is also equipped with industrial control computers and displays at the dispatch station to monitor the real-time operation of trains.Real time video monitoring is carried out for difficult sections of train operation such as turnouts,loading and unloading points,etc.Upon detectiong an obstacle,the electric locomotive obstacle monitoring system promptly issues a safety alert and initiates control measures to decelerate or halt the locomotive as necessary.After the completion of the intelligent construction of the system,the number of equipment operators can be reduced by 23,and the overall economic benefit is 2.07 million yuan,realizing the intrinsic safety of the transition from open-pit to underground mining in Miaogou Iron Mine.The research results can provide guidance and reference for the intelligent construction of mines under similar conditions.
