Abstract: Technological scheme of a layer-by-layer development of a bench (trench) is a system of successively carried out from top to bottom interconnected layer-by-layer technological schemes, each of which represents a number of rigidly geometrically and technologically connected passports of faces (technological charts) of stripping and winning works.
As it was said in the first part of the article, the primary (main) working document for mining foreman and excavator operators is the face passport (flow chart). Therefore, the technological scheme of layer-by-layer mining of the bench is a secondary and not working document. Its purpose is to show the order of change of layer-by-layer technological schemes. Each layer-by-layer scheme is detailed by building up the face sheets at the level of working documentation (drawings). Thus, working out of passports of faces is the basic question at designing of technological schemes of layer-by-layer working out of benches.
Face passport is a drawing of a mining operation, which reflects the interrelation between the parameters of the bench and the excavation machine, taking into account safety rules. The face sheet contains technical, technological and organizational information, which should be reliably and accurately reflected in the drawing.
Since the face passport is a working document primarily for excavator drivers and dump truck drivers, an incorrectly executed or executed blueprint with gross errors can lead to safety violations or inefficient operation of mining equipment. These provisions are taken as a basis for research into the issue of development of structures and parameters of technological schemes for layer-by-layer development of the bench.
This article presents both basic schemes of layer development and schemes of heterogeneous faces for development of two and three layers at their inclined and steep occurrence, as well as the algorithm of their choice.
