匈牙利是欧洲最主要的铝土矿生产国,年产量约为300万吨。匈牙利的铝土矿大多数是地下开采,而且矿床全被含水量大的岩溶层所覆盖,因而匈牙利开采铝土矿所遇到的问题不是大型露天铝矿如何提高效率的问题,而是如何处理在回收软顶板下不规则错断矿床时突然出现的涌水问题。
Hungary is the leading producer of bauxite in Europe with an annual output of about 3 million tons. Most of the bauxite in Hungary is underground and the deposit is covered by a water-rich karst, so the problem with the mining of bauxite in Hungary is not how to improve the efficiency of the large-scale alluvial aluminum but how to deal with it Emerging gushing problems during the recovery of irregularly broken deposits under soft roofs.
