Raspadskaya is Russia's largest coking coal producer, and quality control is critical to its business. It was looking for a solution to ensure that its coal grades do not mix when unloaded by its trucks at warehouses. Mixing grades of coal due to human error can spoil the final product. Coke is an essential fuel and reactant in the blast furnace used in the production of steel. It is produced by heating coal to remove impurities and create a hard, porous material. The company's processing plant cleans the coal extracted from the mine to obtain a concentrate, which is coal, free of impurities and rocks. The raw coal is transported via dump trucks from different manufacturers and is then unloaded into storage bays. If a driver makes a mistake and dumps coal of a particular grade on the wrong pile, the concentrate's quality and yield will fall. This can have a significant impact on the operation's profitability.
