Computer Aided Deposit Evaluation

Introduction:

Objective of Computer Aided Deposit Evaluation is to:

  • Achieve enhanced knowledge of the deposit and ensure its optimum utilization.
  • Ensure cost effective mining operations and raw mix design for effective production planning and extend deposit life.
Coverage:

The evaluation covers the following:

  • Assessment of errors in estimates for various estimations of assay values.
  • Preparation of isopleth and thickness maps for selected grades.
  • Preparation of grade/ tonnage tables for mineral reserves.
  • Preparation of block maps to depict the slice plans of quality.
  • Undertake Quarry Scheduling and Optimization considering various parameters/ constraints to analyze their impact on mineral reserve, deposit life and economics of mining.

Methodology:

The following modular methodology is adopted in executing Computer Aided Deposit Evaluation (CADE):

Part I   :           Preparation of Drill Hole Data Base (DHDB)
Part II  :           Deposit Block Model (DBM)
Part III  :          Quarry Scheduling & Optimization


Benefits:

It helps an investor:

  • Achieve enhanced knowledge of the deposit and ensure its optimum utilization.
  • Ensure cost effective mining operations and raw mix design for effective production planning.
  • Reduce drilling costs, conserve fuel, homogenize product quality and extend deposit life.
