WHAT EVERY MINER SHOULD KNOW
If you've spent any time at a surface mine, you're already familiar with high walls — those towering, unexcavated faces of rock and ore that define the landscape of open-pit mining operations.
These impressive vertical or near-vertical faces can range from just a few feet to hundreds of feet tall, and are a common feature of surface mining operations around the world.
While high walls are a natural part of the mining environment, knowing how to work safely around them is one of the most valuable skills any miner can develop.
INSPECT BEFORE YOU WORK
Before beginning any work near a high wall, a thorough inspection must be conducted. Carefully examine the wall for loose rocks, overhanging materials, and any visible vertical or horizontal cracks.
Pay close attention to boulders, trees, or other debris positioned above that could dislodge and fall without warning. Never assume that because an area looked safe yesterday, it is safe today. Conditions can change overnight.
KNOW YOUR HAZARDS
Weather conditions can dramatically alter the stability of a high wall. Rain, snow, freezing temperatures, and thawing cycles all weaken ground integrity in ways that are not always immediately visible to the eye.
Always ensure your work area is adequately illuminated so you can properly assess ground conditions before and during your shift. Never position yourself between equipment and a high wall — a clear and unobstructed escape route must always be available.
Berms should be consistently maintained at both the base and outer edges of all walls to reduce the risk of falling rock.
REPORT UNSAFE CONDITIONS IMMEDIATELY
Any hazard that cannot be corrected on the spot must be reported immediately to your supervisor. The affected area must be barricaded and clearly posted to warn other workers.
Under no circumstances should any work resume in that vicinity until the unsafe condition has been fully and properly corrected. Do not assume someone else has already reported it.
If you see it, it is your responsibility to act.
ALWAYS WEAR FALL PROTECTION
When drilling or loading shots on or near high walls, safety belts and lines are mandatory. Before beginning work, identify and confirm sufficient anchoring points that can support your weight in the event of a fall.
Inspect your fall protection equipment at the start of every shift. Worn or damaged gear must be replaced immediately — never take chances with equipment that could save your life.
Your awareness, your diligence and your commitment to proper safety procedures are what stand between a productive workday and a preventable tragedy.
