Abstract.The main way to increase the competitiveness of Kuznetsk coals produced by the open method is to reduce overburden works. On the open pits of the southern Kuzbass the flat coal seam strata are developed using transportless technology during overburden works. Open-pit fields are developed in combination: the lower part to the height of 32-44 m is worked out by low-cost transportless technology (producing cost of 1 m 3 of overburden is 22-24 rubles, the upper part -by high-cost transport technology (producing cost of 1 m 3 of overburden is 35-44 rubles) using shovels EKG-10, EKG-12.5, EKG-20 excavators and quarry dump trucks with the carrying capacity of 80-180 tons. The volume increase of the rock that is transferred to the internal dump will improve the economic indicators of coal mining. In addition, due to the flat bedding, the height of the rock mass, which is processed by transport technology, is constantly increasing. At the present time, this has led to the speed decrease in the movement of the working front of the transport zone and, as a consequence, to slowing down the development of transportless. The redistribution of overburden volumes between zones in the direction of increasing the volume by transportless technology will increase the speed of movement of the transport zone (while maintaining the same complex of mining and transport equipment).

All over the world, the topic of green growth is relevant, that is, the growth of economies through the use of modern, environmentally sound, energy efficient technologies, including the use of alternative energy sources. In a modern, dynamically changing society, renewable energy sources are of interest to an increasing number of people. This interest is quite justified, since recently coherent problems of energy and environment are becoming more and more obvious. When discussing emerging problems, the leaders of states and international organizations more often come to the conclusion that in the future these problems can be solved only with the use of environmentally friendly renewable energy sources. The development of green and renewable energy is of particular importance for the Russian industry, in which, on the one hand, the fuel and energy sector occupies one of the main places. On the other hand, the transition to sustainable development is impossible without reducing the impact of energy on the environment, which is intended to contribute to the development of green and renewable energy.
