Abstract
The authors express their deep gratitude to the Head of the Research and Development Laboratory for quality control of iron ore raw materials, Professor A.A. Azaryan, as well as the staff of the Department of Open Pit Mining at Kryvyi Rih National University for their assistance when implementing the scientific developments and their introduction into production.
Highlights
It is distinguished their high level of suitability for implementation and use in the designing of mining operations development in the quarries of PJSC “ArcelorMittal Kryvyi Rih” and PJSC “Southern Mining Factory”
The research results are presented using the example of a stage of the rock pillar mining between the No 3 quarry of PJSC “ArcelorMittal Kryvyi Rih” and the quarry of PJSC “Southern Mining Factory” with involvement into mining the reserves, extraction of which is possible within the existing mining and land allotments
The working project prepared by Pivdenhiproruda [19] considers the development of a rock pillar between the No 3 quarry of PJSC “ArcelorMittal Kryvyi Rih” mining department and the quarry of PJSC “Southern Mining Factory” with involvement into mining the reserves, extraction of which is possible within the existing mining and land allotments
Summary
That is why the purpose of the article is to analyze adjacent quarries as a single industrial-economical system, the integration of which increases as their technologically active zones come closer
