1983年至1986年,湖南冷水江锡矿山矿务局在原南矿充填系统的基础上新建了一套深部充填系统。该系统的一个重要特点是利用国产仪表对尾砂浆的浓度、流量,水泥的给料量和水泥与尾砂混合物的搅拌液位等工艺参数进行自动检测与调节。经试生产证明,该系统运行可靠,有一定的经济效益。 From 1983 to 1986, Hunan Lengshuijiang Mine Bureau of Mines built a new deep filling system on the basis of the former South Filling System. An important feature of the system is the automatic detection and adjustment of the tailing slurry concentration, the flow rate, the feeding amount of cement and the mixing level of the cement and tailings sand mixture with domestic instruments. Trial production proved that the system is reliable and has certain economic benefits.
