Abstract: domestic and foreign experience shows that the most effective in the devel-opment of low coal seams is the plowing. The practice of using plough mechanized complexes in difficult mining and geological conditions has shown that complexes based on complete type supports are the most effective. The support units, in addition to the main purpose of maintaining the top wall, also perform the function of a support for the hydraulic jacks of the ploughing haulage system, which also perform the function of adjusting the position of the ploughing system as the seam gradient. Such a system, with the obvious simplicity of the technical solution, is characterized by the high complexity of the process of adjusting (moving) the ploughing system along the face and its low efficiency. The purpose of the research is to develop a device for adjusting the position of the ploughing system for the seam gradient with special hydraulic jacks located along the face. Research methods: analysis and generalization of information contained in literary sources and determined by timekeeping; analysis of the results of operation of plough mechanized complexes based on complete type supports; structural synthesis. A device has been developed for plough mechanized complexes based on complete-type supports, which corrects the position of the ploughing system by seam gradient. As a result of the tests, a relationship was established between the amount of sliding of the ploughing system and the movement of the face. The displacement value averages 0.125 m per 1 m of face movement. The labor intensity of restoring the normal position of the ploughing system is 348-426 people-min. for one stroke of the hydraulic jack of the device. At the same time, the number of hydraulic jacks providing lifting of the ploughing system should be at least 6. The developed corrective device is highly reliable, provides effective resto-ration of the normal position of the ploughing system along the treatment face and does not restrain the technological process of coal mining.
