Support the stope and to prevent cave-ins. Miners will also use the timber to work from, like makeshift scaffolding.There are two types of timbered-stoping:Square-set stoping. Square-set stoping uses timber that is set into stopes in a square pattern. This is then backfilled with tailings, or mining waste, and a binder like cement.Stull stoping. Stull stoping uses seemingly random timbering, called stulls. The stulls are placed between the foot and hanging wall of the ore vein. Stull stoping is used in mines with strong rock support since the stulls don’t provide much structural support. Backfilling these stopes made by stull stoping with large voids can be extremely dangerous and can cause a mine to collapse.Open Stope MiningThe open stoping mining method is unique in that it does not require artificial support.There are four types of open stope mining:Overhand stoping. Overhand stoping is an open stope mining method that works the ore deposit from the bottom upward. With the drill and blast technique, this is the typical direction used to create a stope.Underhand stoping. Underhand stoping is an open stope mining approach that works the ore deposit from the top down and is used in cut and fill underground mining. This method was more widely used when miners predominantly used hand tools and could rely on gravity to collect ore.Combined stoping. Combined stoping is an approach to open stoping that works the ore deposit from the top and bottom simultaneously.Breast stoping. Breast stoping is an open stope mining method that works the
