NATURE-ORIENTED OPEN COAL MINING TECHNOLOGIES USING MINED-OUT SPACE IN AN OPEN-PIT. PART II: A METHOD FOR SELECTING RATIONAL SEQUENCE OF MINING FLAT DIPPING STRATIFIED DEPOSITS

摘要

A method is proposed for selecting a rational mining sequence with internal dumping for flat stratified deposits, using new principles of the open-pit process-space formation and development. The main criteria for substantiating the mining sequence are geometrical form and development direction of the open-pit space, structure of the working wall and transportation network, internal dumping capacities and mining earthworks volumes.
