Abstract:According to the characteristics of hillside open pit and complicated valley terrain, In this paper, the waste dump has been reasonable located and optimal designed, which effective uses of 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 the economic benefit is remarkable. In order to avoid the barrier lakes caused by the flood in the north of waste dump, the bottom drainage technology is used for draining upriver water catchment and internal water seepage of the waste dump, at the same time, flood control facilities are set up both inside and outside of the waste dump to ensure the security and stability. Finally, the geosynthetic fiber mattress revetment and reclamation measures are used to achieve the purpose of maintain ecosystems and protect the environment.
