Method for predicting changes in characteristics of mine drainage according to time

摘要

The present invention relates to a method for predicting changes in water quality characteristics of mine drainage. The prediction method according to the present invention comprises the steps of (a) measuring a plurality of water quality elements of a mine drainage at predetermined time intervals to obtain an actual measurement value, and (b) calculating a plurality of water quality elements corresponding to a plurality of governing equations (T + N, N = 2, 3, and 4) at the time point T + 1 by inputting the first measured measured value (time point T) (B) obtaining a predicted value of a water quality factor with respect to time by acquiring a predicted value of a water quality factor at a current point of time using a predicted value obtained immediately before in (C) confirming a deviation between the measured value and the predicted value predicted in the step (b), correcting the velocity constant value included in the governing equation to determine the governing equation, and determining the governing equation using the determined governing equation Water quality factor according to time of drainage And (d) predicting the change.
