Face Mapping Underground

Underground face mapping documents geology at the mining front. Access and Safety - Wait for blasting all-clear - Check for loose rock barring down - Adequate ventilation - Communication with operations Mapping Procedure 1. Scale face if required with experienced miner 2. Wash face to improve visibility 3. Mark reference points 4. Map geology onto template 5. Take photographs 6. Collect samples if required Features to Record - Lithology - Vein locations, widths, orientations - Structure faults, shears - Alteration - Mineralization visible minerals - Rock mass quality
