Method to predict underground water
WebThe results of the study indicate that in some cases work in mining is performed in conditions of thermal discomfort, and the values of average labor cost fall within the upper, albeit admissible, limits of thermal load. BACKGROUND Statistics shows that almost half of Polish extraction in underground mines takes place at workstations where temperature … Webpredictions for future longwall panels. Comparisons of numerical predictions with mine measurements of water inflow demonstrate the suitability of COSFLOW in accurately predicting mine water inflow and gas emission into a coal mine. 1. Introduction Reliable water inflow prediction is important for the stability and safety of underground mines.
