黄土区大型露天矿排土场岩土侵蚀及其控制技术的研究

Rock and Soil Erosion and Control Techniques in the Dump of the Large Surface Mine in Loess Area

该文以平朔安太堡露天矿为例，探讨了岩土侵蚀的形式、分布及成因，岩土侵蚀的危害和潜在危险。首次提出排土场岩土侵蚀控制的方针为“以排为主，排蓄结合，调节水分，增强整体稳定性，迅速复垦，恢复植被，建立生物工程相结合的控制体系”，控制技术包括基底处理、平盘边坡防护、滑坡崩塌危险区控制及排土复垦工艺。

Taking Pingshuo Antaibao Surface Mine as an exampl, this paper approached the forms,distribution and developing reasons of dump’s erosion ,and pointed out its hazards and potential danger Also ,we first suggested the principle of controlling rock and soil erosion of dump that is :puttingdrainage first , combining storage with drainage ,regulating water for strengening stability of wholedumpimmediately reclaiming and recovering vegetation ,establishing control system of combining biol-ogy and engineering.The control techniques included treatment of foundation base ,protection of ter-raee and slope,control of slide and slip in danger,and techniques design of dumping and reclaiming.
