Abstract

Precision in survey of large opencast mine and the computational process are the key drivers for attaining actual rock excavated. The study involves the procedure for estimation of differences in volume of excavated area by sectional area method by varying cross-section intervals. Keeping the conceptual embodiment in consideration, fluctuation in the volume of rock excavation has been assessed by varying the spacing between the cross-sections from 10 m to 40 m with a key objective to arrive at selection of suitable interval, maintaining the precision within the acceptable range. Contribution of Artificial Neural Network (ANN) has been applied to strengthen the analysis with respect to relative importance and sensitivity on the parameters influencing volume. The paper expresses the view that denser sectional spacing result in precise outcome close to actuals.
