Abstract:
Purpose. Improvement of the method for determining the width of the area for storing overburden at working off the deep open pit and parameters of formation of the internal dump.
Methodology. Analysis of the existing technological schemes for the formation of internal and external dumps in the developing of open pits in Ukraine. For obtaining the results, the following methods were used: statistical and analytical ‒ while processing the main parameters of modern equipment, which is used in the formation of dumps; mining-geometric ‒ while determining the area of possible shearing of overburden rocks in working an excavator on the dump; grapho-analytical ‒ while plotting graphs and analyzing them.
Findings. Modern technological schemes of forming internal dumps with the use of various types of equipment are analyzed, and the parameters of the area of possible displacement rock in forming dumps with the using of excavators are investigated. Dependences of the parameters of the dump on the dimensions of vehicles and working parameters of the dumping equipment are obtained.
Originality. The analytical dependence of the area of possible stripping of overburden rocks is obtained, which takes into account the angle of internal friction of rocks and the formed slope, as well as the height of unloading dump equipment. The method for determining the parameters of the working area needed for forming an internal dump after working off the open pit of the first turn is improved.
Practical value. The creation of dumps in the drawn open space of pits refers to eco- and resource-saving technologies of development. The construction of an internal dump at working off the mining of deep open pits reduces the burden on the environment. The results of the research and the obtained dependencies allow us to improve the methodology for calculating the parameters of the working areas of deep open pits, taking into account the future formation of internal dumps on them. The dimensions of the areas of internal dumps in forming of several tiers have a great influence on the parameters of the dump and the technology of their formation.
