  • Frances Creek Mine Operations INTRODUCING RPAS INTO MINING OPERATIONS DARRYN DOW - CHIEF MINE SURVEYOR
  • 1. SITE OVERVIEW 2. BUSINESS CASE FOR RPAS PURCHASE 3. TRAINING AND CASA CERTIFICATION 4. RPAS WORKFLOW – FROM REQUESTTO DELIVERY 5. FINAL OUTPUT EXAMPLES 6. SUMMARY AND QUESTIONS
  •  TERRITORY IRON - SUBSIDIARY OF NOBLE GROUP  HAEMATITE IRON ORE - 1.6 MILLIONTONNES P.A.  FRANCES CREEK MINE 25KM NORTH OF PINE CREEK, N.T.  FIRST MINED 1967-1974  REOPENED BYTERRITORY IRON IN 2007  PRODUCT RAILED 180 KMTO DARWIN FOR SHIPPING
  •  COST – SYSTEM COMPARISONS  SAFETY – RISK ASSESSMENT AND BENEFIT ANALYSIS  QUALITY – DATA ACCURACY AND DELIVERY METHODS  EFFICIENCY – CURRENT v’s PROJECTED  REPORT AND APPLY FOR PURCHASE APPROVAL
  •  1st EXPOSEDTO RPAS IN 2011. SUPPORTTO INVESTIGATE  PLATFORM SELECTION -VTOL v’s FIXEDWING  AUTONOMOUS FLIGHT PREFERENCE  INITIAL QUOTATIONSVARIED BETWEEN $45K - $100K  COMPARISON - GPS ROVER - $50K, SCANNER - $240k  COST OF PURCHASE,TRAINING, CERTIFICATION - $57K  COST BENEFIT – EOM REDUCED FROM 100TO 12 HOURS  RETURN ON INVESTMENT– 10 MONTHS
  •  RPAS IS OPERATED BYTHE SURVEYOR INDEPENDENT OF MINING ACTIVITIES ELIMINATING INTERACTION WITH MINING EQUIPMENT AND OTHERVEHICLES  REDUCES HEALTH AND SAFETY RISKS ASSOCIATED WITH CORE SURVEY PRACTICE OF CLIMBING OVER LOOSE AND UNCONSOLIDATED GROUNDTO RECORD DATA  SIGNIFICANTLY REDUCES RISK OF HEAT STRESS, DEHYDRATION, FATIGUE, DUST EXPOSURE AND OTHER POSSIBLE FAI’s/MTI’s ( e.g SOFTTISSUE INJURIES )
  •  ANALYSIS OF RISK ASSESSMENT IDENTIFIED LOW RESIDUAL OUTCOMES FROM RPAS OPERATIONS  COMPREHENSIVE FLIGHT PLANNING WAS IDENTIFIED AS THE KEY CONTROL MEASURE FOR RISK REDUCTION DURING RPAS FLIGHT OPERATIONS  SPECIFIC BENEFITS ACHIEVEDWHEN USED AS RISK ASSESSMENTTOOL OVER HAZARDOUS AREAS AND INCIDENT SCENE EVIDENCE CAPTURE
  • DATA CAPTURE COMPARISON – FIELDTEST NOV. 2012  AREA FLOWN = 7 ha ( 250m x 280m )  FLYING HEIGHT = 110m ( 361 ft )  TIME IN FLIGHT = 9 mins  PROCESSINGTIME = 17 mins report, 131 mins mosaic  PIXEL SIZE OF MOSAIC = 3.45 cm
  • ROM PP1
  • ROM PP1
  • PRODUCT PAD 1
  • PRODUCT PAD 1 WFL55
  • WFL55
  • DTM CREATED IN SURPAC FROM RESULTANT POINT CLOUD
  • DATA CAPTURE COMPARISON –VOLUME RESULTS  VOLUME FROM GPS = 2774 m3  VOLUME FROM RPAS = 2799 m3  VARIATION = +25 m3 ( +0.9% )  POINTS CAPTURED BY GPS = 97  POINTS CAPTURED BY RPAS = 48,705
  •  RPAS PROVIDES POINT CLOUD DATA AND HIGH RESOLUTION IMAGERY CONCURRENTLY  LARGER AREAS CAN BE COVERED IN SHORTERTIME PERIODS AND IN GREATER DETAILTHAN PREVIOUS METHODS USED ON SITE  INCREASESTHE EFFECTIVE DATA CAPTURED BY PERSONNEL IN BOTH QUALITY AND QUANTITY
  •  SURVEYORS CAN COMPLETE OTHER FIELD OR OFFICE TASKSWHILE RPAS SOFTWARE CONDUCTSTHE AUTOMATED PROCESSING CYCLE  CAN BE DEPLOYED RAPIDLY AFTER REQUESTS, e.g. INCIDENT SURVEY, HOWEVER LONGER PLANNING IS PREFERRED  PROVIDES AUTONOMY FOR SITETEAMSTO MANAGE AERIAL IMAGERY CAPTURE AND DISTRIBUTION
