Monitoring of Mining Facilities Using Archival and Modern Aerial Photographs

Abstract

Of great importance are the issues of studying the harmful impact of the extractive industry on the environment, on changes in the landscape of these territories, which, as a rule, are covered with new disturbed lands, polluted water bodies and air. There-fore, the conducted studies are relevant. The aim of the study is to determine the characteristics of the territories where indus-trial mining facilities are located and the features of their changes over time, using images obtained in different ways and dates. The methodology is based on the analysis and analysis of the results of experimental work from the processing of samples taken in different ways and on different dates. The analysis of the obtained data allowed us to determine the requirements for the work on processing such images. Based on the results of the study of the methodology for joint processing of surveys for 1977 and 2021, carried out in fundamentally different ways - photographic and digital, the magnitude of changes in the quarry over this period of time was determined. The obtained values of changes allow monitoring the volumes of mineral extraction and making adjustments to the plans for field development. The scientific novelty of the obtained results lies in the development and testing of a method for determining the magnitude of changes in the shape and size of a quarry over a significant period of time, through the simultaneous processing of images for different dates and obtained in different ways, since at the end of the 20th century only photographic shooting was performed, and today only digital. The analysis of the research results allowed us to conclude that it is possible to use archival aerial photography to study changes in territories. Particular attention was paid to the selection of appropriate software. The practical significance of the conducted research is in obtaining data that allows solv-ing surveying support problems related to the assessment of mineral extraction over a long period of time.
