据了解,国外还没有采用露天水力开采铝土矿的先例。主要是几个大铝业公司操纵着五大洲主要铝土矿的开采权,他们所设计建设的矿山,多数是原生铝土矿,难于用水力开采,对某些能够利用水力开采的堆积、残积矿床也这样做,既能解决开采的技术问题,又为本国制造厂家推销电铲、汽车等矿山设备创造条件。但不能说明堆积、残积型铝土矿床不能用露天水力开采。实际上,一个矿山的采矿方法是由矿山地质和开采技术条件,以及实践经验所决定的。
It is understood that there is no precedent for the use of open-air hydraulic mining bauxite abroad. Mainly a few major aluminum companies operating the mining rights of the main bauxite on five continents, they design and construction of the mines, most of the native bauxite, difficult to use hydraulic mining, for some can use the hydraulic mining accumulation, residual The deposit is also doing so, both to solve the technical problems of mining, but also for domestic manufacturers to promote electric shovels, cars and other mining equipment to create the conditions. But can not explain the accumulation, residual bauxite deposits can not be open-air hydraulic mining. In fact, the mining method of a mine is determined by the geological and mining conditions of the mine and its practical experience.
