Seepage Calculation and Analysis on the Eastern Slope of Yanshan Iron Ore

摘要

Yanshan iron ore open pit, located next to a river channel where quaternary epipedon large and thick covered on bedrock including seepage passage of highly permeable sandy gravel. As seepage engineering measures are necessary to ensure the production safety, the typical eastern slope section of nearby river channel was selected in this paper to make a seepage calculation and an analysis on the characteristics of seepage field and the control effect of anti-seepage measure on seepage field. The effective seepage control measure standards for engineering construction were also obtained through the calculation. The calculation results can provide reference to anti-seepage projects.
