How shall auger machines and other related equipment on which a person is required to work during drilling operations be protected against falling material from the highwall?

• A. With netting only
• B. Protected by heavy gauge screen or equivalent material subject to approval of mine inspection, screen shall permit workmen to keep high wall in view at all times
• C. With wooden barriers
• D. No protection required

Answer: (B)

Protection for auger machines and related drilling equipment must be robust against material falling from the highwall. The best approach is a heavy gauge screen or an equivalent barrier that is approved by the mine inspector. This kind of screen is designed to stop or contain falling rock while still allowing workers to keep the highwall in view at all times, so they can monitor conditions and respond if the wall starts to fail. Netting alone often isn’t enough to stop larger debris, wooden barriers can fail under impact and may hinder visibility, and having no protection at all is unsafe. Using a properly designed screen ensures both safety and visibility, and the approval requirement ensures the protection meets site-specific conditions and regulatory standards.
