Stoping - Wikipedia
WEBStoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. [1] Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.

WEBOpen stoping. This type of mining is used to recover steeply dipping orebodies in competent rock. The ore is removed from the stope as soon as it is mined. Sublevel stoping and big-hole stoping are the important variants in use today. A few examples of commodities mined by this method include iron and lead/zinc. Supported Methods.
Mining - Blasthole Stoping, Ore Extraction, Drilling | Britannica
WEBContents. Home Technology Industry. Blasthole stoping. When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough.

WEBApr 5, 2017 · Cut-and-fill stoping is a flexible method; irregular walls can be followed and stringers or offshoots of ore can be followed and mined into the walls. Waste broken in mining these stringers can be sorted out and left in the fill. Waste inclusions within the ore body can be shot down into the fill if they are small or left in place if large.
