01.概况 No.1 Introduction
尾砂膏体充填和膏体堆存具有安全、高效、节能、环保等优点，在矿业发 达国家被广泛认可并应用。
Tailings paste backfilling and paste storage at surface technologies have the advantages of safety, high efficiency, energy saving and environmental friendliness. They are widely recognized and applied in the mining industry of developed countries.
白音查干多金属矿地处内蒙古西乌珠穆沁旗，矿区以残山丘陵与准平原
草原景观区为主，植被较发育，覆盖程度较高。矿体为多金属矿，主要含 有铅、锌、银、铜、锡等。
Baiyinchagan Polymetallic Mine located in the Xiwuzhumuqinqi, Inner Mongolia. The mine area is mainly composed of hills and prairie landscape and widely covered by the vegetation. Polymetallic ore bodies have been discovered, with the main contained metals of lead, zinc, silver, copper and tin.
设计生产规模为5000t/d，分两个系统，铅锌系统2500t/d，铜锡系统 2500t/d，采用地下开采方式。主斜坡道开拓，分段空场嗣后充填采矿法 和上向水平分层充填采矿法，全尾砂膏体充填和膏体堆存。
The designed production rate is 5000 t/d, with two processing streams comprising a 2500 t/d of Lead-Zinc system and a 2500 t/d of Copper-Tin system. The underground mine uses a main ramp development system and sublevel open stoping and a bottom-up cut and fill method. The unclassified tailing paste backfilling system and paste stockpiling systems have been established.

01.概况 No.1 Introduction
2014年6月，中国恩菲完成该矿初步设计，随后开展施工图设计，同年开 始建设。2016年9月，矿山基建完成，目前处于试生产阶段。
In June 2014, China ENFI had completed the preliminary and detailed designs for the mine and started infrastructure construction at the same year. In September 2016, the mine completed infrastructure construction and turned into trial production.
中国恩菲于20世纪90年代初开始在国内进行膏体充填技术的研究与应用，
设计的金川镍矿、铜绿山铜矿、会泽铅锌矿、冬瓜山铜矿和谦比西铜
矿等矿山先后建成膏体充填系统并投入运行，该技术在我国得到迅速发展。
In the 1990 s China ENFI begun to research and develop the paste backfilling technology (Yu, 2011), and successively established and put into operation paste backfilling systems in the Jinchuan Nickel Mine, Tonglushan Copper Mine, Huize Lead-Zinc Mine, Dongguashan Copper Mine and Chambishi Copper Mine. The technology has been rapidly developing in China.

01.概况 No.1 Introduction
目前，我国尾砂膏体堆存技术仍处于起步阶段，在运行尾矿膏体堆存系统 的规模化矿山主要有乌奴格吐山铜钼矿和包头白云鄂博西矿。
But at present, paste storage technology in China is still in preliminary stage, only two paste storage systems are in large scale application. Which are Wunugetushan Copper, Molybdenum Mine and Baiyunebo West Mine.
02. 全尾砂膏体充填系统 No.2 Unclassified Tailings Paste Backfilling System
正常生产时，2台深锥浓密机同时工作，料浆制备及输送系统2套工作1套 备用。 Two sets of deep cone thickeners operate simultaneously together with 2 sets of slurry preparation and transportation systems during normal production, at the same time, The third set of slurry preparation and transportation systems standby. 单套系统制备能力（80-100）m³/h，每套均可用于全尾砂胶结充填和非 胶结充填。 The preparation capacity of each deep cone thickener is 80 to 100 m³/h. Each set can be used for unclassified tailings cemented as well as uncemented filling.
全尾砂膏体充填系统包括膏体制备、输送和采场充填。选矿厂生产的全部 尾砂送至充填搅拌站，经充填搅拌站内的深锥浓密机浓缩后，制备合格的 充填料浆，通过浓料输送泵送至井下采场空区进行充填。
The unclassified tailings paste backfilling system consists of paste preparation, transportation and stope filling. All the tailings has been sent to the filling station for tailings thickening by using deep cone thickeners, and then delivered to the underground working area through slurry pumps and pipelines.
