Use of instrumental methods of measurements of ash and water content as well as coal caloric value in systems for monitoring and control the quality parameters of coal products was presented. Examples of systems for stabilization of ash content and maximization of coal production were given. Systems of single jigs as well as simple and complex technological systems were discussed. Special attention was paid for optimization of production of steam coal mixtures using an automatic quality control system.
