      <abstract xml:lang="ru">
        <p>Измерение смещений руды взрывом является одной из ключевых компонент системы контроля качества на любом горнорудном предприятии позволяет получать необходимую для определения местоположения рудных контуров точность. Около 15 лет назад в Австралии была разработана система мониторинга, позволяющая персоналу рудника проводить трехмерные измерения смещений рудных блоков при каждом взрыве. Проведенные исследования показали, что смещение рудных блоков крайне изменчиво и характеризуется полным отсутствием детерминированной составляющей. Следствием этого является то, что моделирование смещений рудных контуров в процессе взрыва будет неточным, а наилучшие результаты для горнодобывающего предприятия могут быть достигнуты лишь путем прямого измерения смещений. Рассмотренная в статье технология измерения смещений рудных контуров основывается на трехмерных векторах смещений, полученных в различных частях взрываемого блока, характеризуемых отличными смещениями. Очевидно, что точность определения положения рудных контуров после взрыва пропорциональна числу измерений, проведенных на блоке. В настоящее время технология контроля смещений на базе ВММ-системы активно используется мировыми горнодобывающими компаниями, ее применение снижает потери и разубоживание руды. В 2017 г. на Олимпиадинском ГОКе начато опытное внедрение ВММ-системы, система внедряется в нескольких российских горнодобывающих компаниях.</p>

        <p>Measurement of ore movements by blast is one of the key components of the quality control system at any mining enterprise, which allows to obtain the accuracy necessary for determining the location of ore contours. About 15 years ago, a monitoring system was developed in Australia that allows mine personnel to make three-dimensional measurements of ore blocks movement at each blast. Studies have shown that ore blocks movement is extremely variable, and it characterized by a complete absence of a deterministic component. The consequence is that modeling ore contour movements during the blast will be inaccurate, and the best results for the mining enterprise can only be achieved by directly measuring the movement. The technology of measuring ore contours movements considered in the article is based on three-dimensional movement vectors obtained in different parts of the blasted block, characterized by different movements. It is obvious that the accuracy of determining the ore contours position after the blast is proportional to the number of measurements made on the block. Currently, the movement control technology based on the BMM system is actively used by global mining companies, its use reduces losses and dilution of ore. In 2017, the pilot implementation of the BMM system was started at the Olympiadinsky GOK, and the system is being implemented in several Russian mining companies.</p>
