摘要
针对焦家金矿北翼破碎矿体的地质条件和采矿生产安全现状,通过经济效益、效率分析,本着"技术先进、经济合理、安全可靠"的原则,确定选择下向进路机械化充填采矿法,产量增加3倍,吨矿成本降低了1.44元,实现了真正的高效、安全生产。
According to the geological condition of the broken orebody in the north limb of Jiaojia gold mine and the present situation of the mining production safety,through analyzing the economic benefits and efficiency,with the principle of advanced technique,reasonable economy and reliable safety,we selected the filling into the path of mechanized mining method.The output increased three times,the cost of the ore per ton decrease ￥1.44.And we re-alized a goal of efficient and safety mining production.
