【摘要】：膏体充填技术是充填关键设备突破和井下采矿需求共同发展的产物,该技术在我国得到迅速推广应用。随着膏体技术应用逐渐成熟,其正朝着精细化研究方向发展,旨在提高充填质量、降低充填成本。叙述了膏体充填概念、工艺特点及技术优势,介绍了膏体充填技术在国内外的发展历程和应用现状。对新型胶凝材料、全尾砂脱水技术、膏体流变学、硬化膏体多场性能和膏体微观性能等热点方向研究现状进行了分析。同时,对新疆伽师铜矿和赞比亚谦比希铜矿膏体充填系统做了介绍。最后,提出了膏体充填技术在中国的发展趋势。
[Abstract]:Paste filling technology is the product of the breakthrough of filling key equipment and the development of underground mining demand. This technology has been rapidly popularized and applied in China, and gradually matured with the application of paste technology. It is developing towards the direction of fine research, in order to improve the quality of filling and reduce the cost of filling. The concept of paste filling, technological characteristics and technical advantages are described. The development and application of paste filling technology at home and abroad are introduced. The new cementing materials, the whole tailings dehydration technology and the rheology of paste are introduced. The research status of multi-field properties and microcosmic properties of hardened paste is analyzed. At the same time, the paste filling system of Jiashi Copper Mine in Xinjiang and Chubich Copper Mine in Zambia is introduced. Finally, the paste filling system of Jiashi Copper Mine in Xinjiang and Chubisch Copper Mine in Zambia is introduced. The development trend of paste filling technology in China is put forward.
