Stripping of Water containing Fine Powder Sand Layer in Loose Slope at Iron Open pit Mine

赵店子铁矿在露天开采中遇到了含有含水粉细沙层的松散覆盖层。生产中应用液压反铲 -汽车采装及分条剥离、超前疏干的剥离工艺较好的解决了松散覆盖层的剥离问题 ,取得了较好的经济效果。文中详细论述该法的使用情况 。

Loose covering layer that consisted of water containing fine powder sand layer was encountered in the opercasting at Zhaodianzi Iron Mine.The stripping problem of this loose covering layer was well solved by hydraulic back shovelling truck hauling,advance drainage and stripping in slices,and good econimic results were achieved.The method is described in details and it is of reference value to the similar mines.
