超高台阶土场稳坡扩容增源新技术

A new technique of stabilizing slope, enlarging volume and augmenting resource of high bench dumping site

为了矿山环保及减少土地占用面积 ,根据高台阶土场动态形成过程 ,利用散体动力学研究高台阶排土场的高稳定机理 ,系统探讨了土场增高扩容、扼制泥石流、底部泄流等新技术 ,为排土场在稳定条件下增加堆高、开辟用地新来源、根治泥石流、治理原表土基底创造了条件 ,对保护国土资源、根治因土场失稳而引起的矿山灾害具有重要意义 .

There exists urgency of protecting environment and decreasing landholding, in order to solve the problems, the authors use the dynamic forming course of the damping sites and the dynamics of broken rocks, have studied the mechanism that the high bench dumping site takes on highly stability and the new technology, including dumping site rising and enlarging capacity,controlling mud rock flow and building bottom sluiceway systematically. The theory and the technology have been successfully applied to some large sized dumping sites such as Changba Lead Zine Mine, Nanfen Ferric Mine and other large sized open pit mines, where great profits have been made. And it is significant that the land resources are protected, and the disaster caused by landslide of dumping site is controlled thoroughly. [
