This report is a comparative analysis of mine productivity in major coalfields of the western world. Mine productivity in terms of labour productivity is a suitable and important criterion for coal mining performance and as such widely quoted. However, it is often misinterpreted and used for comparison in an appropriate way. In addition, the factors affecting mine productivity are not fully understood in their existence or their weight.
In this report, various means of defining mine productivity are assessed and a proper definition is established. The factors affecting mine productivity are evaluated in a theoretical way and by representative mines as examples. The influence of political and economic factors, the 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 and the utilisation and efficiency of labour input is discussed in detail. The potential for and the limits of productivity improvements are demonstrated. Comparisons can be drawn for representative mining conditions of 25 mines and 14 coalfields in 9 countries of the western world (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 and case study reports on the 25 mines provide material for an in-depth analysis of mine productivity in specific, representative cases.
