and introduction of the sub level caving (SLC) mining system has started. The bottom of the third production level is set at 123 m above sea level. The distance from level 250 is divided into 4 sublevels at 221, 186, 155 and 123 m. In the new level, ironore will be mined following the northward dip of the deposit (approx. 8085 degrees) from W towards E in each sublevel .

· Where block caving is the mining method employed haulage levels generally are loed to come under or near the bottom of the ore body, and in modern practice high columns of ore up to 300 feet or more are undercut and caved in one lift. Opening of grizzly and undercutting levels above the main level is a part of stope development that will be discussed later.

Abstract: LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years. Throughout the years, LKAB has improved this mining method to stay competitive in a tough international iron ore market. Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease .
