Abstract

The article considers the features of the distribution of technological indicators (product output, content and extraction of copper) by size classes, the main factors influencing the crushing process are identified and regression dependences of productivity on influencing factors are received. The parabolic nature of the dependences of the output of crushed rock on the size class is established. The high adequacy of the obtained models was confirmed and the most promising classes of rock size for copper extraction were determined. The obtained results and models will allow to develop a generalized model of the process of native copper mining and to implement this process with rational and optimal parameters. Also, the received models will allow to carry out an estimation of productivity of a research site of processing of raw materials of basalt quarries.

Highlights

Historical and archeological data indicate that Volyn native copper was well known to the ancient Slavs
The first thorough written data on Volyn native copper appeared in the Polish geological literature in the late 1920s, some publications as early as 1887 already mention Volyn native copper
The performed studies made it possible to establish that for lava breccia, the regularity of the yield of crushed mass from the size class is parabolic (R2 = 0.926), and the distribution of the copper yield from the size class obeys the cubic parabola law (R2 = 0.9682)

Summary

Introduction

Historical and archeological data indicate that Volyn native copper was well known to the ancient Slavs. This is evidenced by the names of places (Midsk, Medishche, etc.) of Old Slavic origin (mid - copper), tools from ancient settlements and ancient basalt mines in the basin of the Goryn River. In addition to Volyn copper, several other rich manifestations of native copper have been discovered in Ukraine relatively recently. All these previously unknown ore occurrences were found on the Ukrainian Shield. Rare finds of native copper are known in the Carpathians, Azov, Donbass and Kryvyi Rih
