Abstract: For the coal sorting, a griddle model with a rope moving field has been developed by the Siberian Federal University scientists, the design of moving field is protected by the Russian patent. Due to the simplicity of the design, in comparison with the inertia and self-balancing griddles used, the proposed griddle provides the production of high-quality coal with less energy consumption. To determine the economic efficiency of using a griddle with a rope moving field, the main parameters are calculated in comparison with the griddles used. The calculation of annual operating costs, which are included in the cost of finished products - graded coal. For this purpose, the annual salaries of maintenance personnel, repair costs, electricity, depreciation expenses for the proposed griddle and griddles used at mining enterprises are calculated. Thus, the amount of savings obtained by using a griddle with a rope moving field is calculated in comparison with an inertial griddle GIL and a self-balancing griddle GISL, at the same productivity. According to the results of calculations, the proposed griddle is economically more profitable to use for coal sorting, which also has less capital investment for manufacturing. Thus, the use of griddle with a rope moving field for coal sorting, due to its lower cost and ex-operational costs, will reduce the costs of producing high-quality coal and reduce the cost of finished products.
