Advance planning before augering is done shall insure that no hazards are created affecting active underground workings. Auger mine workings and holes drilled shall be located to prevent which occurrences?

• A. Interference with ventilation
• B. Water inundation
• C. Interference with ventilation and water inundation
• D. Subsidence of surface

Answer: (C)

Planning ahead for auger operations centers on protecting underground workings by choosing locations that keep the ventilation system effective and prevent water from entering. If auger holes are placed poorly, they can create unintended air paths that bypass or disrupt the mine’s ventilation, causing gas buildup or reduced airflow where workers rely on proper dilution and removal of methane or other hazards. At the same time, drilling into or near water-bearing zones can open a route for water to flood underground workings, endangering stability, equipment, and safety. By locating auger mine workings and drilled holes so they do not interfere with ventilation and do not invite water inundation, you minimize these dual hazards and maintain safer underground conditions. Subsurface subsidence, while important in its own right, is not the hazard this planning step targets as directly as ventilation integrity and water ingress.
