在凡口铅锌矿采用的尾砂充填或尾砂胶结充填采矿法中,由于充填骨米为分级后的粗粒级尾砂,其产率和利用率低,致使充填料严重不足,加之传统尾砂充填混合料浆的离析和水泥流失现象严重,因此,必须寻求解决这些问题的新途径,而开展高浓度全粒级尾砂胶结充填新工艺及其装备的研究正是为了这一目的。本文系统地介绍了这一新工艺的流程和工业试验情况,并对充填质量和经济效益进行了分析与评价。 In the tailings or tailings cemented filling mining method adopted by the Fankou lead-zinc mine, due to the grading of coarse-grained tailings after grading, the yield and utilization rate are low, resulting in a serious shortage of filling materials. In addition, the traditional Therefore, it is necessary to find new ways to solve these problems. It is for this purpose that the research on new technology and equipment of high concentration full-scale tailings cementation and filling should be carried out. This paper systematically introduces the process of this new process and industrial test conditions, and the filling quality and economic benefits were analyzed and evaluated.
