There are several other systems of quarrying that are used in various parts of the world, including:
Room and pillar: In this system, the quarry is developed as a series of interconnected rooms, with pillars left in place to support the overlying rock. The rooms are typically large, rectangular areas that are separated by pillars.
Inclined bench: This system involves the creation of a series of inclined benches, or terraces, on the side of a hill or mountain. The quarry is then developed by removing the rock in a series of horizontal slices, or benches, starting at the top and working downward.
Open-pit: In this system, the quarry is developed as an open pit, with the rock being extracted from the ground using large earth-moving equipment. This is typically used for large-scale operations, such as extracting aggregates or coal.
Sub-level caving: This system involves the creation of a series of underground levels, or sub-levels, in the quarry. As the rock is removed from the sub-levels, the voids are allowed to collapse, creating a natural caving effect. This system is typically used for extracting large, solid blocks of stone, such as granite.
Block caving: In this system, large blocks of stone are extracted from the quarry by creating a series of underground tunnels. As the blocks are removed, the voids created are allowed to collapse, creating a caving effect. This system is typically used for extracting large, solid blocks of stone, such as granite
