摘　　要：针对山坡型露天矿、复杂山谷地形特点,对排土场合理选址、排土工艺优化设计,有效利用了地形优势增强了排土场稳定性。通过增加了排土场堆积容量节约了土地资源,就近集中排弃达到缩短运距目的,经济效益显著。为避免汛期排土场北侧形成堰塞湖,采用底部泄流体技术,疏排上游汇水及排土场内部渗水,同时在排土场内外分别设置防洪设施,保证了排土场的安全稳定。最后利用土工网垫护坡及复垦措施,实现了维护生态系统、保护环境的目的。According to the characteristics of hillside open pit and complicated valley terrain, a waste dump field has been reasonably located and optimally designed, which effectively uses the terrain advantage to enhance stability, saves the land resources by increasing the dumping accumulation capacity, shortens the load distance by concentrated dumping nearby, and achieves remarkable economic benefit, in order to avoid the barrier lakes caused by the flood in the north of the waste dump field, the bottom drainage technology is used for draining upriver water catchment and internal water seepage of the waste dump field, at the same time, flood control facilities are set up both inside and outside of the waste dump field to ensure the security and stability. Finally, the geosynthetic fiber mattress revetment and reclamation measures are used for the purpose of maintaining ecosystems and protecting the environment.
