When the ore is particularly valuable, the walls and pillars are often removed at a later stage and the roof of the chamber is allowed to cave in. This technique is known as robbing.
如果矿石特别宝贵，矿壁和矿柱常在最后回采，让采场顶板冒落。这一技术叫矿柱回采。
5.
This method can improve the ore extraction rate and reduce the ore dilution rate and has been found to be a rational mining method for the mine.
该方法提高了矿石的回采率，降低了矿石的贫化率，为矿山寻找出一条合理的开采方法。
