Abstract

The paper presents a theoretical analysis of highwall destruction by blasting. Peculiarities of blasting in high faces at open-pit mining operations in Russia are analyzed. New approaches to drilling processes in high faces are proposed. Possibilities of application of walking machines for downward digging (walking excavators) are described.
