(I) Proved reserves: -It is based on geological evidence at 200 mt. In this method lines drawn of 200 mt interval trenches, mine working and borehole extension.
(ii) Indicated reserved:- It is based on the geological continuity at 1000 mt interval. Demarcate of outcrop at an interval of 1000 mt.

Calculate the reserve in situ up to various cut of line and grade of coal.
Reserved quantity in tonees= Plan area × Thickness of seams× Sp. gravity of coal

Note:- For net reserve 10% deduct.
