Bilan T. Methods and means of economic and mathematical modeling of coal industry development under the world market conditions.

The new balance-optimization method of the required mines' production capacity evaluation is proposed under conditions of extraction sources competition and taking into account energy security limitations. The economic and mathematical model of coal industry development under the world market conditions is proposed. The model takes into account competition of supply sources allowing the evaluation of cost-effective amounts of coal products production and import, as well as the best ways and sources of supply, subject to demands of energy security. The subsystem of coal import, as a component of the economic and mathematical model of coal industry development, is proposed to consider possible differences in transport technologies. The modeling approach is proposed to take into account the energy security factors in the problem of determining the levels of coal base development.
