分段空场法是我国冶金地下矿山空场法中应用较好的一种采矿方法,具有生产能力较高,放矿工艺简单,矿房回采的矿石贫化率、损失率较低,易于实现采准、生产探矿相结合,坑木消耗小,回采成本低,采场通风条件好等优点。在矿石、围岩均稳固的急倾斜中厚、厚矿体中,分段空场法是一种好的采矿方法,引入采场振动出矿技术的振动出矿分段空场法,可以获得更好的技术经济效果。
Segmented empty field method is a kind of mining method which is better applied in the underground mine in China’s metallurgical underground mine. It has the advantages of high production capacity, simple ore drawing process, low ore dilution rate and low loss rate, and is easy to realize Adopt the combination of production and prospecting, pit consumption, mining cost is low, the stope ventilation conditions are good. In the steeply steep middle-thick and thick ore bodies with stable ore and surrounding rock, the sub-section method is a good mining method. By introducing the vibro-out-section method, Better technical and economic results.
