Dust Control In Hard Rock Mines. What You Can’t See Can Kill You. Dust Control In This Mine Is A Large Complex Problem. Many items discussed in this presentation requires problem solving at all levels of an operation.
What You Can’t See Can Kill You.
Many items discussed in this presentation requires problem solving at all levels of an operation.
It may require engineering, operations, or maintenance groups to assist to ultimately solve.
It requires a total team effort from all underground personnel & other site-wide groups.
Dust can cause health related issues whether it is a short acute related health problem or a long term systemic problem like silicosis.
Prevention of dust is everyone’s problem. We all breath the same air, if we don’t take care of it. In other words: “It can kill you.”
Requires Good Regular & Consistent Maintenance
Factors that can lead to high dust levels on drills:
Lack of Proper Maintenance
Failure to use water
Inadequate quantities of water
Plugged water holes in drill steels
Dull drill bits
Poor Maintenance on dust collector systemsDrill Dust Control
All require regular maintenance & attention.
Disabling dust control systems are a bad practice that can cause long term health threats.
Large Strides can be made to improve dust during this cycle.
Note: Predampening & washing down of rock surfaces in shotcreting zone will greatly improve adhesion of product & eliminates a lot of dust that can be liberated during pneumatic application of product.
Dust Control for machines like roadheaders usually depend on some degree of dust cloud confinement.
Ultimately it is the objective of the safety department to do away with mandatory respiratory protection for all underground personnel. This will only be possible by diligent efforts of all personnel underground.
There are definitely in roads that need to be made. Some of it is behavioral. Some of it is improvement in conditions that create dust releases. It will require everyone’s help & active participations to solve.
You say, “What does that have to do with dust control?
What conditions can drive behaviors?
How do we correct them?
What behaviors can drive conditions?
How do we correct them?
The Key to solving this problem is what?
You may not be able to control how your fellow worker will react.
The Key is being able to control how you react.
Proactive Safety can help solves problems.
Collectively if we all choose to do the most productive correct solution to this problem,
It won’t belong to until we all have eaten this elephant.
It starts with the first bite.
