Classification of ore mining systems

Abstract

Due to the differences not only in the methods themselves and their details, but also in the principles of development of ore and coal deposits, drawing up a single classification of development systems for both is impractical. An attempt to compile such a general classification turned out to be unsuccessful due to complexity and contradictions, and the proposed classifications, to the detriment of one of the specialties, ore or seam, were practically unacceptable. For ore mining systems, which have long been an independent and most important branch of mining in the national economy of the Union, a simple independent classification of ore mining methods is necessary.
