Every stope and development opening shall be provided with at least one ______ of appropriate length and diameter, properly pointed or sharpened.

• A. Hammer
• B. Crowbar
• C. Pinch/Pry Bar
• D. Pick

Answer: (C)

In underground mining, a tool designed for leverage and prying is essential in every stope and development opening. A pinch bar, sized appropriately and with a pointed or sharpened end, provides the necessary leverage to pry, wedge, or manipulate rock safely when passages need to be cleared, opened, or secured. The pointed or sharpened tip helps locate cracks or start a prying action without needing to strike the rock with a hammer, and the right length and diameter give you enough reach and strength to work from a safe stance. A hammer, by contrast, is for striking and doesn’t serve the same leverage function. A crowbar can pries but isn’t the specific tool referenced in this requirement, and a pick is used for breaking rock rather than prying or moving it.
