  • 矿体“二次圈定”在排山楼金矿的应用……武昌胜,李传迎
  • 摘 要:随着开采深度的不断加深,排山楼金矿的矿体分支复合、尖灭再现的现象逐渐增多,致使采矿损失率、矿石贫化率波动幅度变大。以排山楼金矿的10个采场为例,通过采场“二次圈定”前后矿体的对比,绝大部分采场矿体在“二次圈定”前后变化较大,说明采场“二次圈定”在地质日常工作中不可或缺。通过采场“二次圈定”有效地降低了采矿损失率、矿石贫化率,直接提高了地质资源的利用率,为排山楼金矿带来了可观的经济效益。

    Application of "twice delineation" of orebodies in Paishanlou Gold Mine……Wu Changsheng,Li Chuanying

    AbstractWith increasing mining depth in Paishanlou Gold Mine,phenomena like orebody branches merging and recurrence after wedging out become frequent,making loss and dilution rate vary larger.The paper takes 10 stopes from Paishanlou Gold Mine as the research subject,compares the orebody through "twice delineation".Most stope orebodies vary before and after the "twice delineation",showing the"twice delineation" is indispensible in everyday geologic work.The"twice delineation" effectively reduces mining loss and ore dilution rate,directly increases the utilization rate of geologic resources and renders considerable economic profits to Paishanlou Gold Mine.

    Keywords:mine geology; orebody;twice delineation; stope; mining loss rate; ore dilution rate; Paishanlou Gold Mine
