在胶结充填生产中,由于充填工艺的要求或是生产条件的限制,常常需要把水泥制作成水泥浆,用管道输送到井下搅拌站,和砂石混合制备成混凝土。目前,水泥浆的制备一般采用机械搅拌的方法。这种方法虽然工作比较可靠,但是设备体积较大,作业卫生条件较差,仃止充填作业时需要处理较大量的剩余水泥浆。因此,在设计金川有色金属公司龙首矿粗骨料胶结充填系统时,提出了射流引射制浆的技术方案。 In cemented filling production, due to the filling process requirements or production conditions, often need to make the cement into a slurry, pipelines to the underground mixing station, and gravel mixed into concrete. At present, the preparation of grout generally adopts the method of mechanical stirring. Although this method is more reliable, but the larger equipment, poor sanitary conditions, Dingding filling operations need to handle a larger amount of excess cement. Therefore, in the design of Jinchuan Nonferrous Metals Company Longshou coarse aggregate cementing filling system, put forward jet jet pulping technology program.
