sublevel caving mining method

The sublevel caving SLC mining method has evolved over the last 100 years The method was first used in the early 1900s in soft iron ore mines in Minnesota and Michigan USA Hartman and Mutmansky 2002 It represented an evolution from top slicing but was initially highly labour intensive and required heavy timber support
