      <abstract xml:lang="ru">
        <p>Хода подземной полигонометрии прокладываются с целью создания в горных выработках системы пунктов с известными координатами и для решения горнотехнических задач. Поскольку такие хода являются основой для решения большинства маркшейдерских задач, от их каче­ства и своевременности выполнения зависит успешность маркшейдер­ского обслуживания горных работ в целом.</p>

      <abstract xml:lang="en">
        <p>Underground polygonometer courses are laid in order to create a system of points with known coordinates in mine workings and to solve mining engineering tasks. Since such runs are the basis for solving most of the surveying tasks, their quality and timeliness depends on the success of the surveying service of mining operations as a whole.</p>
