摘要
程潮铁矿-430^-500 m矿体将使用崩落法和充填法协同开采,以同时兼顾技术经济和采场稳定性,为此以技术经济子系统和采场稳定性子系统构建了崩落法和充填法协同开采的协同度测度模型来进行方案选择。结果表明,基于协同度测度理论,3种采矿方案中方案3上向水平分层充填法和无底柱分段崩落法协同开采最优,方案1下向水平分层充填法和无底柱分段崩落协同开采次之。
Abstract：Caving method and filling method will be used to cooperate the mining of -430-- 500 m ore body in Chengchao iron mine, so as to consider the technical economy and stope stability at the same time. Through the technical economy subsystem and stope stability subsystem, the coordination degree measurement model coordinating the caving method and filling method was established for the selection of filling method. The results showed that based on the synergetic degree theory, the cooperate mining of upward horizontal cut-fill mining method and non-pillar sublevel caving was superior among the three mining schemes, while the cooperate mining of downward horizontal cut-fill mining method and non-pillar sublevel caving was the sec- ondary.
