چکیده انگلیسی مقاله This paper analyses the possibility of increasing the efficiency of loading the destroyed rock mass into the face scraper conveyor by the lagging screw actuator of the shearer in the process of coal mining in the complex mechanized treatment faces of coal mines. It was taken into account that the most significant influence on the loading efficiency of coal is exerted by the dimensions of the cross-sectional area of the loading window, the distance between the screw and conveyor and the height of the bottom of the conveyor. Non-traditional technical solutions are proposed that reduce the negative impact of the gap between the screw and the conveyor on the efficiency of coal loading by the lagging screw actuator of shearers and increase the degree of filling of the conveyor groove. Technical solutions contribute to the formation of a rational section of the cargo flow in the trough of the downhole conveyor and, therefore, increase its productivity. The results of modeling the process of loading coal onto the face conveyor by an auger actuator with an additional loading device are presented. Evaluation of the effectiveness of the proposed constructive technical solutions for the interface unit in the loading area confirmed an increase of 2.94 times the maximum capacity of the screw executive body for loading coal onto the face conveyor while 2.7 times less specific energy consumption during loading.
