UPDATE ON THE

DEVELOPMENT OF A BOREHOLE GRAVIMETER FOR MINING APPLICATIONS

SEIGEL, CHOUTEAU, GIROUX & NIND

applications of bh gravity in mining
Applications of BH Gravity in Mining

Remote Detection

  • Massive Sulphide Deposits
  • Other Types of Metallic Deposits
  • Non-Metallic Deposits
  • Verification of Surface and Airborne Gravity Anomalies

Bulk Density Determinations and Applications to Mining

  • Deposit evaluation
  • Improved grade control
  • Relative local rock strength
  • Monitoring integrity of dams and tailings ponds
gravilog development
GRAVILOG Development
  • Three year development & testing
  • Funding:
    • Industry (CAMIRO)
      • CVRD Inco, BHPB, Areva & Schlumberger
    • Canadian Government (IRAP)
    • Scintrex
  • Work Plan
    • Product development at Scintrex
    • Modelling software at École Polytechnique
  • Start: Oct 2005
  • Field Tests in Boreholes: mid 2008
gravilog system test program
GRAVILOGSystem Test Program

BENCH TESTS

  • Individual components tested prior to assembly
  • Complete prototype system

SHAKE – DOWN TESTS

  • Borehole near Lindsay (Sir Sanford Fleming)
    • Proper functioning of all Gravilog modules & sensors
    • S.D of one minute measurements
    • Repeatability
    • Debugging
    • Efficient logging procedures

OPERATIONAL TESTS IN SPONSORS’ BOREHOLES

gravilog bhg for mining applications
GRAVILOGBHG for Mining Applications
  • Development nearing completion
  • Modeling software complete
  • Industry sponsors’ boreholes: mid 2008
  • Production logging system: January 2009
