在基鲁纳开采的大多数矿石是由分段崩落法获得的,该法是该矿确认的使用很好的采矿法。由于追求充分增加产量,所以,变更是不可避免的,且部分矿石目前是用大直径深孔分段法(la-rge scale sublevel stoping)——超级采矿法开采的。作者描述了这种采矿法和为采矿研制的凿岩设备。
Most of the ore mined in Kiruna is obtained by the sub-caving method, which is a well-used mining method identified by the mine. Changes are inevitable due to the pursuit of a substantial increase in production, and some of the ore is currently mined using the la-rge scale sublevel stoping-super-mining method. The authors describe the mining law and the rock drilling equipment developed for mining.
