使用絮凝剂的主要目的是使水砂料和胶结料很快沉淀、胶结,避免离析,保证充填料在采场中均质,减少排水中的固体量。澳大利亚蒙特埃萨(mountIsa)矿采用尾砂和胶结充填,尾砂粒度组成为;-0.104毫米粒级占100%。其中-0.010毫米粒级占5～7%,-0.037毫米粒级占70%,在不使用絮凝剂的情况下,充填后20小时铲运机即可进采场作业,采场的排水基本是清 The main purpose of using flocculant is to make water sand material and cementing material precipitate quickly, cementing, avoiding segregation, ensuring filling material is homogeneous in stope and reducing the amount of solid in drainage. Tailings and cements are used in the Mount Isa mine in Australia. The tailings have a particle size of -0.104 mm and a particle size of 100%. Of which -0.010 mm particle size accounted for 5 to 7%, - 0.037 mm particle size accounted for 70%, without the use of flocculant, 20 hours after filling scraper can enter the stope operation, stope drainage basically clear
