Mine Productivity

This report is a comparative analysis of mine productivity in major coalfields of the western world.

Various means of defining mine productivity are assessed and a suitable definition established. Factors affecting mine productivity are evaluated in a theoretical way and by taking representative mines as examples.

These factors include:

  • political and economic influences;
  • geographical context of a mining operation;
  • geological parameters and characteristics of a coal deposit;
  • mining technology and engineering factors of both underground and surface mining;
  • the utilisation and efficiency of labour input.

The potential for and the limits of productivity improvements are demonstrated. Comparisons are drawn for representative mining conditions of 25 mines in 14 coalfields in 9 countries (6 mines in Australia, 1 in Canada, 1 in Colombia, 1 in France, 4 in the FRG, 3 in the RSA, 1 in Spain, 2 in the UK and 6 in the USA).

Country overviews provide the essential background for a comprehensive understanding of the absolute values as well as past and likely future developments of mine productivity in the individual coalfields and countries. Case study reports on the 25 mines provide material for an in-depth analysis of mine productivity in specific, representative cases.
