To the statement of laboratory researches of the process of scooping of rock mass
Abstract
The process of scooping or gripping with a bucket the rock mass, which is to some extent in a disturbed state of adhesion between the particles, is one of the links in the chain of processes for the extraction of minerals. However, it has not received sufficient coverage in the technical literature. Related areas, such as the theory of soil cutting, are also comparatively poorly developed. Research works on loading machines do not go further than the registration of the mode of operation of machines, do not investigate the compliance of the machine to the face, do not analyze the individual stages of loading and therefore cannot give justification to the theoretical concept of the loading process, the magnitude and nature of possible forces and calculation methods of newly designed loading machines. Experiments with models of the elements of the working elements of loading machines (published so far) are only the first steps in the systematic study of the scooping process, since the conditions of the experiments cannot correspond to the actual operating environment of loading machines.
