Frontal self-loading of coal in longwalls is the most important means of fulfilling the five-year plan of the coal industry in 4 years

Abstract

Implementation of mechanization of coal loading in the working face is one of the most important problems of the Soviet coal industry in the 4th Stalin Five-Year Plan. In the "Law on the Five-Year Plan for the Restoration and Development of the National Economy of the USSR for 1946-1950" it is written: "In order to implement the established program for the growth of coal production, construction and increase in labor productivity - mechanize labor-intensive processes in the coal industry in every possible way, in particular, ensure the widespread implementation of work on the mechanization of coal loading and rock loading." There are three main possible ways of mechanization of coal loading in the working face: Partial mechanization of loading, i.e. loading onto the conveyor not all of the extracted coal, but some of it. Full mechanization of loading, performed by specialized loading machines. Complex mechanization of coal loading and extraction; the executive machine in this case is a mining combine or cutting-cutting-bulking machine. The second and third methods require the creation of highly sophisticated designs of bulk machines and mining combines.
