What shall be visually examined immediately before starting any mining work?

• A. Roof, face and ribs
• B. Roof only
• C. Face only
• D. Ribs only

Answer: (A)

Before starting any mining work, you must visually check all areas that could affect stability: the roof above, the face where material will be mined, and the ribs along the sides. This full inspection helps you spot loose rocks, cracks, or signs of movement, and to verify that supports and rock bolts are in place and in good condition. Any one area can hide hazards that could lead to a roof fall or rib collapse once work begins, so examining only one part risks missing danger. By looking at roof, face, and ribs together, you ensure the working place is as safe as possible before you proceed.
