摘要
通过分析姑山采场的水文地质和工程地质条件,探讨了利用粉细砂含水层和砂卵砾石含水层之间的粉质粘土层建造台阶式防渗帷幕的可能性,以消除姑山采场东北帮边坡因地下水和青山河水在边帮中可能对边坡造成渗透变形的隐患,为姑山采场安全开采东北帮优质铁矿石创造条件,也为姑山矿实施可持续发展提供技术支持。
Based on the analysis for the hydrogeological and engineering geological conditions of the Gushan open stope, the possibility of building anti-seepage stepped curtain in silty clay layer between silt-sand aquifer and sandgravel aquifer is discussed. The goal of the research is to settle the potential problem of seepage deformation caused by groundwater and Qingshan river at the northeast of Gushan stope. It would provide the conditions for exploiting high -grade iron ore resource in security and offer strategic support for sustainable development of Gushan Iron Mine.
