Mining in Siberia-U.S.S.R. with U.S. Manufactured Construction Machinery

The permanently frozen earth (Perma-Frost) that covers much of Siberia has greatly hindered the development of the natural resources located in this vast arctic region. Because of the U.S.S.R.'s state of development of adequate-sized machinery to penetrate the Perma-Frost, the Soviets have been forced to turn to western technology for machinery to mine and develop their resources. This paper describes some of the United States machinery in which the U.S.S.R. is interested.
