干式与削壁充填相结合采矿法在二道沟金矿的应用

介绍干式与削壁充填相结合采矿法在二道沟金矿的应用情况,它解决了破碎岩矿体的采矿问题,为其它矿山类似矿体的回采提供实践经验。干式与削壁充填相结合采矿法是结合普通干式充填和削壁充填法的特点,总结出的一套新的采矿方法。干式与削壁充填相结合采矿法选取了普通干式充填法的采矿损失率和贫化率低,适应矿体形态的各种变化,充填料来源广泛与便宜的特点;同时也选取了削壁充填法架设溜矿井,矿石由溜矿井放出的特点;干式与削壁充填相结合采矿法也采用普通削壁充填采矿法的采切与回采工艺。

The Application of the Resuing Stoping Combined with Dry-packing Method in Erdorgou Gold Mine

This essay mainly introduces the application of the resuing stoping combined with dry-packing method in Erdorgou Gold Mine.The mining method of reusing combined with dry back filling has solved the mining problem on fragmentized rock ore,and provides practical experience in the stoping of other similar ores for other mines.This method is a new mining method,which is summarized in features of common dry packing and resuing stoping.From the common dry-packing method,it has selected the characteristics of low mining dilution ratio,low loss ratio,applying to various changes of ore＇s modality,inexpensiveness and extensive availability of the fillings.Meanwhile,selected the features from resuing stoping method,it also sets up the raise chute for ores drawing and adopts the technology of mining and stoping.
