摘　　要：总结了兰尖铁矿采用高台阶排土的生产实践、高台阶排土的安全技术要求、保障安全生产的技术措施及经验教训。实践表明 ,高台阶排土可实现岩土的就近排放 ,有着显著的经济效益 ,但从设计阶段就应做好排土场工程水文地质、排土场稳定性评价及安全防范工作 。The application of high bench dump in the production at Lanjian Iron Mine,the technical requirements of its safety,the technical measures ensuring the safe production and the related experiences and lessons are summarized.The practice has shown that high bench dump can realize the nearest dumping of the waste rock and bring remarkable economic benefits.However,the evaluation of the engineering hydro geology and the stability of the waste dump and the safety guaratee work should be made as early as in the designing stage so as to avoid the occurrence of safety accidents.
