上游式尾矿库尾矿堆积体沉积规律

Abstract Based on the actual investigation and analysis of drilling samples the deposition law of upstream tailings pond is summedup. The main data source is laboratory test data including the system particles analysis of 11drilling samples. The data is processed bygraphic method. Results show that along the vertical direction with depth increasing the particle size of the accumulation body generallydwindles along the horizontal direction the farther from the outfall the smaller the particle size is. This article provides basic reference fordeeply understanding the horizontal and vertical deposition law of tailings pond and further p further analysis of tailings dam stability.院上游式尾矿库 数据处理 垂直方向 水平方向 沉积规律Key words upstream tailings data processing vertical horizontal deposit law中图分类号院TD22 文献标识码院A 文章编号院1006-4311（2014）15-0065-031
