PLC 由于其可靠性高、抗干扰能力强、编程简单、功能完善、实用性强,在矿山的自动控制系统中应用越来越广泛。某矿新建760 m 竖井.井筒淋水较大,在井底-70m 处形成井底水仓,计划用2台75 kW 的水泵将水提至-650 m 中段,利用该中段已有的排水系统将水排至-220m,然后排至井口,作为选矿车问及其它车间的生产用水.实现水资源的循环利用。
PLC because of its high reliability, anti-interference ability, programming is simple, functional and practical, and more and more widely used in mine automatic control system. A new 760 m shaft was set up in a mine, where the wellbore was heavily flooded to form a bottom silo at a depth of -70 m. Two 75 kW pumps were planned to raise the water to the middle of -650 m. Utilizing the existing drainage system The water is discharged to -220m, and then discharged to the wellhead, as a dressing cart to ask other workshops for the production of water to achieve the recycling of water resources.
