What are the side walls of a mine referred to as?

• A. Rib
• B. Pillar
• C. Roof
• D. Gob

Answer: (A)

The side walls of a mine are called "ribs." In mining terminology, the rib refers specifically to the exposed faces of rock on the sides of the mine an excavation. These features maintain the structure of the mine and are critical for safety, as they help support the roof and control potential rock falls. Recognizing the role of the rib is essential for ensuring the integrity of mine operations and for the safety of the personnel working within the mining environment. Pillars, on the other hand, are the columns of material left to support the mine roof, while the roof is the top surface of the mine. Gob refers to the mined-out area that has been backfilled or collapsed.
