盘区上向水平分层干式充填采矿法在金矿脉开采中的应用

AN APPLICATION OF PANEL UPWARD HORIZONTAL CUT-AND-DRY FILLING METHOD INTO GOLD VEIN MINING

大水清金矿曾用留矿法、削壁充填法开采高品位急倾斜矿体，贫化、损失率较大，且存在不安全因素。为此，试验用盘区上向分层干式充填采矿法进行回采，取得了较好的效果。本文论述了这一采矿方法的选择与设计及回采和充填工艺的主要特点。

The shrinkage method and the cut wall filling method were used to mine the steep orebody with a high grade in Dashuiqing gold mine, which resuled in greater dilution and loss as well as the unsafe. As viewed form this, the panel upward horizontal cut-and dry filling method has been tried to use for this orebody mining, with a better results. This paper describes the selection and design of this mining method and the main features of stoping and filling technology.
