摘　　要：猫场铝土矿矿区设计规模为120万t/a,是贵州某大型铝企业中长期发展的主要资源保障。该矿区距企业氧化铝厂64 km,交通极为不便,一旦矿山投产,解决铝土矿石的运输问题显得尤为重要。长距离管道化运输工艺上世纪90年代起已在我国少数矿山成功投运,与铁路及公路运输相比,具有运输距离短,基建投资少,不占或少占地,不污染环境及不受外界条件干扰等诸多优点。通过对国内外浆体长距离运输管道成功实例的广泛调研,该企业拟采用长距离矿浆管道输送方式进行运矿,本文重点讨论猫场矿区管道化输送方式的技术论证及拟建设方案的运行指标。Maochang Bauxite Mine with the designed capacity of 1,200 kt/a, situated in a remote area and 64 km from an alumin- ium oxide plant is the main resource to ensure the long-term de velopment of a major aluminum business in Guizhou. As it is ex- tremely inconveniently located, once the mine is put into operation, solving the issue of bauxite transportation is very impor- tant. The long distance pipeline transportation technology has been successfully operational in a few mines in China since the late 1990. Compared with other transportation （such as railway, highway）, it has advantages of short transport distance, less cap- ital investment, no or less occupation of land, no environmental pollution, no exposure to outside interference and others. Through the extensive research of the successful domestic and in- ternational examples of long distance ore slurry pipeline transportation technology, the enterprise intends to transport the ore by the long distance slurry transportation technology. This paper focuses on the technical demonstration for the long distance pipeline transportation technology in Maochang Bauxite Mine and the operation index of the construction scheme.
