About the operating mode of bulk handling mechanisms

Abstract

The last two decades have been a period of intense and continuous work for the coal industry of the USSR in the field of solving the problem of complex-mechanized coal mining and, above all, the problem of mechanization of coal loading in working faces. In the development of technical methods and the design of new machines for this extremely important purpose, Soviet mining science and technology have achieved significant success and occupy a leading place. Our designers and inventors have an indisputable priority in the matter of creating loading machines and longwall mining combines, which are the first in world practice to be produced and used in series. Based on the accumulated experience in the design and operation of loading mechanisms in our country, it became possible to formulate and successfully resolve in the fourth five-year plan the most important national economic task: "...to mechanize labor-intensive processes in the coal industry in every possible way, in particular to ensure the widespread implementation of work on the mechanization of coal loading...". Both specialized bulk machines and bulk units of mining combines were designed in the Soviet Union according to a wide variety of schemes. Initially, designers and machine builders sought to create machines with constant mechanical characteristics, designed for use in any mining conditions. In our coal industry, the desire for universality of mining mechanisms determined persistent attempts to build a machine suitable for any conditions of cleaning excavation.
