Abstract: The results of successful operation of long-head technology introduced for the first time in Russia are presented. From the lava 50-03 400 meters long, equipped with a remote control system of high-performance machines and mechanisms, when working out the formation 50 in the conditions of the mine. V. D. Eletskogo 1567067 mined tons of coal per month. The article describes the method developed by the authors to assess the correspondence between the design daily production of coal from lava, the technical characteristics of the selected geological conditions of machines and mechanisms, the length of the lava and its daily rate of movement. The results of calculations by this method allowed to justify the necessary speed of daily lava movement and the corresponding organization of labor in the lava to ensure the design daily coal production. The results of time-based observations of the performance of technological operations in the lava showed that in some periods of time at a high speed of the combine, the speed of lava fastening was insufficient for manual control. In such cases, these operations were transferred to the management, control and regulation of the remote automated system. Studies of technological processes in the lava 50-03 show that the use of long-alloy technology increases the productivity of the working treatment face, reduces the length and dispersion of the workings, significantly changes the ventilation, the manifestation of mountain pressure, etc.
