摘要
通过使用脱水后的干尾砂对废弃的露天采坑进行回填,可以减少溃坝事故的发生,同时降低矿山安全事故发生的几率,同时对土地资源和水资源进行有效节约,从而对生态环境起到保护作用。使用干尾砂充填露天采坑使经济、社会以及生态三方面效益得到保障。
Through the use of dehydrated dry tailings of abandoned open pit backfill, can reduce dam accidents, and reduce the probability of mine safety accidents, at the same time, land resources and water resources effectively so as to save, to protect the ecological environment.
