Which tool is recommended for pulling down rock safely?

The recommended tool for pulling down rock safely is a bar of suitable length. This tool is specifically designed to provide the leverage required to dislodge and pull down rock, making it an effective and safer option in mining operations. A bar can be used to apply force in a controlled manner, reducing the risk of sudden rock falls and ensuring that the miner maintains control over the process.

In contrast, while a jackhammer is effective for breaking rock, it is not designed for pulling down material and could create instability in the surrounding rock structure. A shovel, although useful for moving loose material, lacks the necessary leverage to safely pull down rock. Similarly, a rock drill is intended for creating holes in rock rather than dislodging or pulling it down, making it unsuitable for this particular task. Therefore, using a bar of suitable length allows miners to work more efficiently and safely when needing to pull down rock.
