摘　　要：为了解决石碌铁矿露天转地下开采过程中稳定生产、采场地压管理、采场防汛抗洪等问题,矿山采用自然崩落和回填覆盖岩层来管理地压、采取“截、疏、挡、排、防”的措施治理矿井涌水,实施露天与地下协同开采,有效地防止了涌水对采矿生产的影响、保证了原矿产量的平稳过渡。In order to solve the problems of stable production,stope ground pressure management,stope flood control and flood fighting in Shilu Iron Mine during transition from open pit mining to underground mining,the Mine adopts natural caving and backilling overburden rock stratum to manage ground pressure,adopts measures of"intercepting,dredging,blocking,draining and preventing"to control mine water inrush,and implements open-pit and underground collaborative mining,which effectively prevents the influence of water inrush on mining production and ensures the smooth transition of raw ore output.
