The Extraction Forecast for a Hard Coal Mine

Abstract

This publication presents a method for forecasting the annual amount of coal extraction for a mine. The forecast of extraction amount was based on data from an actual hard coal mine. It included an analysis of retrospective data on sales quantity, calculation of regression coefficients of the mathematical trend model and extraction amount for the next year. The planned extraction amount was corrected for the most probable forecast error. In addition, a forecast extraction plan for the analyzed mine was provided for individual months, in two variants.
