Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Abstract: The Aitik open pit mine, located in northern Sweden, currently faces a substantial production increase, which has necessitated a review and update of design guidelines. This work pointed at the possibility of increasing interramp slope angles a few degrees, which, in turn, requires an improved bench slope design, most notably blasting techniques.
