Mine Opening or what is commonly known as Pit plays an important role in Underground Coal Mining. It serves as the entry / exit point in transporting men, machinery, power etc. inside the mine; maintains ventilation; serves as the point of transportation of coal from the mine to the surface, and many more. In short, it plays the role of a gateway to the underground coal mine. The decision regarding size, site, number and type of mine openings to be created is one of the major decisions for a new mine. In case of expansion of an existing mine, the existing openings influence the decision regarding new additional openings to a large extent. A number of factors like Size and shape of the property, Availability of land, Presence of surface features, Geo-mining conditions, Number of seams to be worked on etc. influence the choice of mine opening or Pit. In this paper, we have worked on the' Size and shape factors of the property' and have done a geometrical analysis on the total effort required to mine the entire area considering Pits at different positions for various shapes of the mine boundary.
