Improvement of rock-breaking tools of heading-and-winning machine of potash mines
Perm National Research Polytechnic University, 614990, Komsomol'skij prospect, 29, Perm, Russia
Conducted a statistic research of the construction features of heading-and-winning machine actuator members for the extraction of potash ores. It is shown that increasing the efficiency of the destruction process of a potash massif with the cutters of heading-and-winning machine actuator members is possible by means of the potential cross-cutting technique. The methods of potash layers destruction by cross cuts were considered. Designs of the heading-and-winning machine actuator members that implement the cross-cutting scheme of potash massif are presented.
