苏联黑色冶金部所属露天铁矿排土场堆存有大量的硬岩剥离废石。对其定性特点分析表明,大部分适于加工成建筑碎石。露天铁矿一般都属于大型采选公司管辖,处于铁路专用线发达的已开发区内,并使用现代化高效率的采矿运输设备。由于这些因素的存在,各采选公司很有可能成为潜在的非金属建筑材料的厂家。 The open pit iron ore dumps belonging to the Soviet Union’s Black Metallurgical Department stockpiled a large amount of hard rock stripping waste rock. Analysis of its qualitative characteristics shows that most of them are suitable for processing into building rubble. Open-pit iron mines are generally under the jurisdiction of large mining companies, which are located in developed developed railway lines and use modern and efficient mining and transportation equipment. Due to these factors, mining companies are likely to become potential non-metallic building materials manufacturers.
