摘要： 在露天转地下过渡期，由于露天地下同时生产的岩移干扰，经常导致安全生产条件差和产量衔接困难.针对露天转地下过渡期露天开采境界内底部矿量、地下开采挂帮矿的实际生产条件，系统地研究了地下开采与岩移特点，提出了应用诱导冒落技术控制挂帮矿地采岩移的方法，不仅改善了露天地下安全生产条件，而且扩展了露天地下同时开采时间与空间.这一方法应用于小汪沟铁矿，有效解决了露天转地下过渡期产量衔接的难题，并实现了安全高效开采.

关键词: 露天转地下, 诱导冒落, 岩移控制, 产量衔接, 安全生产

Abstract: Due to mutual interferences between the open pit & underground mining operations during the transition period from open pit to underground mining， poor safety production and difficult production continuation occur much more frequently. Aiming at the production conditions of ore-body at the open pit bottom and hanging-wall ore-body of underground mining during transition period， a method was proposed to control the hanging rock caving with the induced caving mining technology through the systematic study on the underground mining and rock caving. In this way， the safety conditions of open pit & underground mining could be improved， and the time and space of open pit & underground mining are also extended. The proposed method was adopted in Xiaowanggou Iron Mine to solve the problem of production discontinuation. The applied results show that a highly efficient and safe mining is realized during the transition from open pit to underground mining.

Key words: transition from open pit to underground mining, induced caving, rock caving control, output continuation, safety production
