The present invention relates to a method for maximum utilisation of heat altered coal (Jhama) for coke making comprises the steps of crushing the heat altered coal (jhama) to covert a size of 0.200-0.400 mm; crushing the convention coal to covert a size of 90% below 3.2 mm; mixing the heat altered coal (Jhama) to conventional coal in the proportion 3-5% and 97-95%; adding 0.1% phenolic resin binder to the blend; making the blend in the form of a cake under stamp charging and carbonization of the cake at a temperature of 1100°C for 5 hour in an oven characterized in that the crushing of Jhama reduces the heterogeneity among the component of coal blend and increases the Coke Strength value after Reaction(CSR).
