摘要
在矿岩特别破碎、地压很大的条件下,金川镍矿通过20多年的生产实践和科研工作,应用下向胶结充填采矿法开采3~5万m ̄2的连续、大面积矿体取得了成功。本文对二期工作大面积开采范围的矿柱留设、开采顺序、多阶段开采等问题,通过矿岩稳定性分析提出了具体的对策。
Under extra broken ore-rock and stronger geopressure, Jinchuan Nickel Mine appliesdescending cement filling mining method to mining continuous 30~50 thousands m ̄2 largetract ore body and achieves success through production practice and scientific research formore than 20 years. This paper presents some concrete countermeasures by analyzing ore rock stability for pillar keep, mining series and multistage mining method of large tractmining secondary project.
