METHOD OF LAYER BY LAYER MINING OF COMPLEX-STRUCTURE DEPOSITS OF SOLID MINERALS Russian patent published in 2017 - IPC E21C41/26 E21C47/00 E21C27/24 

FIELD: mining engineering.

SUBSTANCE: method can be used for open mining of mineral deposits with nonuniform distribution and complex configuration of ore bodies. The method includes milling of rock array with layers of fixed width and variable depth, selective extraction of rock layers with nonuniform distribution and complex configuration of rock in a plan and section, different qualitative and physico-mechanical characteristics of rock, formation of rock mass of controlled granulometric and qualitative composition loaded in dump trucks, supervision of dump trucks loading process control with the help of automatic control system and evaluation of rock mass quality, including sensors and information processing system installed on cantilevers behind working member of the milling machine, the sections of rock mass are preliminarily differentiated in layer by layer extraction of the array in a plan by elements by integrating average values of coverage area with fixed width of the milling machine working member, supervision and control of differentiated loading of dump trucks by loaders.

EFFECT: increased performance, reliability and expansion of process efficiency of mining operations.
