The main research content and conclusions are as follows: (1) The main object of this study on paste filling slurry for high concentration tailings cemented filling industrial pumps and industrial filling pumps is the high concentration slurry of graded tailings or full tailings as aggregates in a certain mine. The physical and chemical properties of tailings are studied as the basis for studying slurry performance. Research on the physical and chemical properties, particle size distribution, settling performance, permeability, and other aspects of tailings The physical and chemical properties of tailings are stable, with good settling but poor permeability. The graded tailings have a more reasonable combination of particle size and fineness compared to full tailings (2) Multiple levels of factors such as ash sand ratio and concentration were selected for comprehensive experiments on the mix proportion, in order to study the influence of tailings slurry mix proportion on the strength of paste filling bodies formed by filling industrial pumps and industrial filling pumps Based on experimental data, range analysis and variance analysis were used to qualitatively and quantitatively analyze the influencing factors of paste filling for filling industrial pumps and industrial filling pumps, providing a basis for quality control measures of paste filling for filling industrial pumps and industrial filling pumps The optimal ash sand ratio that meets the requirements of filling industrial pumps and paste filling mining processes using industrial filling pumps was obtained through fitting analysis (3) In order to measure pipeline transportation parameters more accurately and effectively, China is developing mineral resources内蒙古呼和浩特充填工业泵配件、工业充填泵配件、尾砂膏体充填泵配件填泵进行膏体充填系统,料浆制备系统设置于地表,废石破碎系统,搅拌系统和泵送充填工业泵和工业充填泵进行膏体充填系统均设置于井下,料浆制备系统通过自溜充填工业泵和工业充填泵进行膏体充填管道与搅拌系统的进料端对接,废石破碎系统的出料端与搅拌系统的进料端对接,泵送充填工业泵和工业充填泵进行膏体充填系统与搅拌系统的混合料出口对接,料浆制备系统用于制备全尾砂胶结料浆,废石破碎系统用于对井下废石进行破碎.该装置可充分利用井下废石进行胶结充填工业泵和工业充填泵进行膏体充填,能使废石不出坑,大幅度减少废石运输提升成本,提高废石综合利用率,并结合已有全尾砂胶结充填工业泵和工业充填泵进行膏体充填系统,实现尾砂料浆+废石的混合高浓度料浆泵送充填工业泵和工业充填泵进行膏体充填. 基于工程流体力学,流变学,两相流输送理论等相关理论,利用试验研究,理论分析,数值模拟等研究方法,针对某矿山高浓度尾砂胶结充填工业泵和工业充填泵进行膏体充填料浆自流输送技术应用的实际问题,对高浓度尾砂胶结充填工业泵和工业充填泵进行膏体充填料浆进行系统,深入研究,主要研究内容和结论如下: (1)本文研究高浓度充填工业泵和工业充填泵进行膏体充填料浆的主要对象是某矿山分级尾砂或全尾砂作为骨料的高浓度料浆,对尾砂进行物理化学性质研究做为研究料浆性能的基础,从尾砂的物理化学性质,粒度分布,沉降性能,渗透性能等方面进行研究.尾砂的物化性能稳定,沉降性较好而渗透性较差,分级尾砂粒度粗细搭配较全尾砂更为合理.
