SELECTION AND CALCULATION OF PARAMETERS DEVELOPMENT SYSTEM

Course project is provided by the program of discipline "Technology of open pit mining" for students of directions 60721500 - "Mining Engineering (by branches)".The course project considers the issues of deepening system of development with longitudinal preparation of pit ledges for inclined and steeply falling ore deposits of a layer-shaped form, occurring in the thickness of rocky rocks and having as covering rocks moraine deposits. The methodology provides for excavation of rock mass by an excavator of ECG type with road transportation.The final goal of the work is to calculate the parameters of the development system, the productivity of the open pit for ore and overburden and the calculation of the fleet of excavators.Methodical instructions are considered and approved at the meeting of the department "Mining" (Minutes 11 from "25" June 2024) and recommended for publication in the open press.
