鞍钢铁矿山废石综合利用的研究和应用

Comprehensive utilization of waste rock in Anshan iron and steel mine： research and application

系统介绍了鞍钢铁矿山在废石碾压尾矿坝、公路基层贫混凝土、道路基层废石混铺块碎石、建筑材料和场地回填等方面利用采场废石的成果和应用实例，重点说明废石碾压尾矿坝、公路基层贫混凝土两种新技术在理论研究、工业试验等方面的突破，并通过实例说明其大规模应用的可靠性。

Waste rock was successfully used in Anshan Iron and Steel Mine to build compacted tailings dam, make lean concrete road base, pave gravel road, and also to be used as construction materials and site backfilling, etc. Application examples were presented in this paper, with highlighting technological breakthroughs is theoretical research and industrial applications in two areas, i.e., using waste rock to build compacted tailings dam and make lean concrete road base. By way of example, the reliability of large-scale applications of the new technological breakthroughs was illustrated.
