A comparative analysis and study was conducted in the laboratory on the strength and settlement performance of paste filling bodies using full tailings and graded tailings filling industrial pumps, as well as industrial filling pumps, based on the accessories for filling industrial pumps, industrial filling pumps, and tailings paste filling pumps in Harbin, Heilongjiang Province According to the experimental results, at an initial concentration of 40%, the settling performance of graded tailings is superior to that of industrial pumps for filling paste with full tailings and industrial filling pumps The effect of increasing the ash to sand ratio on improving the strength of paste filling in industrial pumps and industrial filling pumps is that full tailings are superior to graded tailings. In the early stage of curing, graded tailings are superior to full tailings, but in the later stage of curing, the paste filling in industrial pumps and industrial filling pumps with full tailings is significantly stronger than graded tailings Meanwhile, in terms of improving the mechanical strength of paste filling bodies using industrial filling pumps and industrial filling pumps, the three factors are curing age>cement sand ratio>concentration With the rapid development of modern technology and industrial production, the scale of mineral resource development has also rapidly expanded. The resulting industrial waste such as tailings has become increasingly harmful to the environment. At the same time, the global resource situation is becoming increasingly severe. Improving mineral recovery rates and recycling of mining waste have received high attention from the whole society. Using tailings to fill industrial pumps and industrial filling pumps for paste filling mining sites is an effective way The high concentration fully tailings cemented filling industrial pump and industrial filling pump for paste filling have the advantages of high filling capacity, less dehydration, and high strength of paste filling. Continuous slurry production of high concentration fully tailings and pipeline transportation of high concentration fully tailings slurry are key technologies among them Therefore, how to improve the continuous slurry concentration and reduce the resistance loss during the transportation process of paste filling using industrial pumps for full tailings filling and industrial filling has become a focus of research in this field This article first summarizes the development and current status of paste filling mining methods using industrial pumps for high concentration tailings filling and industrial filling pumps in metal mines, and introduces several representative methods黑龙江哈尔滨充填工业泵配件、工业充填泵配件、尾砂膏体充填泵配件据,在实验室进行全尾砂与分级尾砂充填工业泵和工业充填泵进行膏体充填体强度及沉降性能的对比分析研究.根据试验结果:在起始浓度(40%)下,分级尾砂的沉降性能要优于全尾砂充填工业泵和工业充填泵进行膏体充填体.增大灰砂比对于提升充填工业泵和工业充填泵进行膏体充填体强度的效果:全尾砂要优于分级尾砂,在养护初期时,分级尾砂优于全尾砂,而在养护后期,全尾砂充填工业泵和工业充填泵进行膏体充填体要明显强于分级尾砂.同时,3种因素对于提高充填工业泵和工业充填泵进行膏体充填体力学强度效果而言,养护龄期〉灰砂比〉浓度. 随着现代科技和工业生产的高速发展,矿产资源的发展规模也迅速扩大,随之而产生的尾砂等工业废弃物对环境的危害也日益严重,同时全球资源形势日趋严峻,提高矿产回收率和矿业废弃物回收利用受到全社会的高度重视,利用尾砂充填工业泵和工业充填泵进行膏体充填采场是一条有效途径.高浓度全尾砂胶结充填工业泵和工业充填泵进行膏体充填以其充填工业泵和工业充填泵进行膏体充填能力大,脱水少,充填工业泵和工业充填泵进行膏体充填体强度高等优点,高浓度全尾砂连续造浆和高浓度全尾砂料浆管道输送是其中的关键技术.因而如何提高全尾砂充填工业泵和工业充填泵进行膏体充填连续造浆浓度和减少输送过程中的阻力损失成为本领域研究的重点. 本文首先综述了全尾砂高浓度充填工业泵和工业充填泵进行膏体充填采矿方法在金属矿山应用研究的发展和现状,介绍了几个具有代
