Abstract
The article reports research findings in the area of open pit coal mining and substantiates alternative technologies based on new technological and organizational principles of open pit mining. Using the method of geometrical analysis of an open pit mine field and technological design of mining systems, stage-wise mining technologies have been developed for the case when mining front advance is changed. Such technologies ensure the improvement of a wide range of technical-and-economical and ecological performance of an open pit mine. The main flow charts of the mining sequences are interconnected with natural-technological groups of deposits, that influence cross-wise configuration of an open pit (ultimate contour) and structural characteristics (parameters) of working areas and generate geometrical type of an open pit field.
