“…Besides, it is necessary to take into account the number of coal beds (bed series) and parameters and structure of the series. If parameters of the bed series have been studied to a certain extent by domestic and foreign scientists Tanaino and Cheskidov, 1999;Vukotic et al, 2013;, the series struc ture is still poorly studied, especially for prospective areas. Meanwhile, it significantly affects both the structure of dumps (number of tiers, etc.)…”

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).

The features of three- and four-tier internal dumps capacity calculation with the additional capacity preparation in the dump tiers

Abstract. The paper deals with the task of increasing the volume of rock placed in the internal dump. For that it is necessary first to analyze the existing technology of internal dumping, and then to determine the height of rock tiers being cut in the transport area. Analyzing the mining on the southern pits of Kuzbass it was found that now mostly three-tier dumps are piled. But for placing the extra volume of rock in the internal dump it will be required to pile dumps with more than three tiers.
