摘　　要：金川镍矿通过２０多年的生产实践与科学研究，在矿岩特别破碎、地压很大的条件下，全面积３～５万ｍ２矿体应用下向胶结充填采矿法进行连续开采并取得成功。作者在总结经验的基础上，对二期工程大面积开采范围的矿柱留设、开采顺序、多阶段开采问题提出了具体意见。With mining practice and scientific research for twenty years,a greatsuccess is achieved in continuous mining by using undercut-and-fill method in alarge area of 30000-50000m￣2 under the condition of broken ore/rock and highground pressure.In the paper, some valuable opinions for designing of ore pil-lar, extraction sequence and multi-level mining in the large exposure areaare presented.
