【 摘 要 】

The question is the experience of studying the wear resistance of mining machines in arctic conditions. Nikolay Tarasov investigated the wear during the penetration of excavations in rocks with negative temperatures. The importance and prospects of similar studies are discussed, taking into account the plans for the exploration of outer space. According to the corporation "ROSCOSMOS" not frozen rocks on the planets of the solar system are found only in the equatorial zone. An analysis is made of the wear characteristics of working tools of mining machines in the development of rocks with temperatures ranging from -9 to -110°C. Made suggestions: to reduce the abrasive wear of the working tool, new approaches to the solution of the problems of wear resistance must be applied; to make an analysis of the possibility of using nonmaterial to increase the wear resistance of working tools of mining machines; taking into account the prospects of cosmonautics, to use the permafrost rocks of the Arctic zone as a testing ground for studying the wear resistance of rolling machines.
