Abstract

Survey plays a vital role in computation of actual volume excavated. Precise computation of opencast excavation is of prime importance as it affects the quantity of mineral/coal and in turn economy. The paper covers the methodology encompassing the concept and procedure for estimation of volume of irregular excavated geometry by section method on varying section orientation. The same approach has been correlated with field measurement done in New Akashkinari mine of Jharia Coalfield. Susceptible aspects like type of software used, process of preparation of cross sections, position of sections, and interval between two sections are discussed to assess the cause for variation in volume computed for the same input data.
