This report summarizes the results of a study to characterize and quantify the occurrence and impact of outby haulage delays on production in US underground coal mines. An instrumentation system employing digital data loggers was used to acquire data for over 500 belt shifts in six mines. Observers collected section production data and section delay data to supplement the haulage database. A statistical data reduction system was applied to develop statistics on failure rates and delay lengths. A production impact model was developed and applied to analyze the effect of reducing delays and implementing engineering changes to the haulage systems. Analytical investigations of the relationship between delays and mine characteristics were conducted, and the impact of feeder-breakers and bunkerage, and the addition of longwall units to existing mines was investigated. The study provides a quantitative information base on underground belt haulage delays for use by mining companies and mining researchers.
