全尾砂胶结充填技术研究与应用

The Research and Application of Whole Tailings Cementation Filling Technique

针对江西银海矿业公司现有充填工艺全尾砂细泥含量多,充填料浆水泥离析现象严重所致的胶结全尾砂充填采场脱水难、充填体强度偏低等问题,通过加强相关充填技术和管理的措施,保障井下工作的安全,有效控制地压活动,充分地回采矿体,降低矿石损失率和贫化率,实现了尾矿再利用,为类似矿山提供了借鉴意义。

In view of the present filling technology with the problem of dehydration of the fill pit, low filling boy strength and others, which is caused by whole tailing with high slime content, the filling slurry with serious cement segregation in Jiangxi Yinhai mine company, the company is strengthening the relevant filling technology and manage- ment measures, so as to protect the safety of underground work, effective control of ground pressure activities, fully stopping ore body, decrease the rate of ore loss and dilution, achieve the tailings recycling, which provides reference for similar mines.
