      <abstract xml:lang="ru">
        <p>Приведена методика проведения натурных испытаний временной крепи, представлены результаты определения напряжений и нормальных усилий в сводовой части и боковых элементах стальной крепи. Выполнена оценка вертикальных нагрузок на крепь. Установлено, что при установке крепи на расстоянии 16 м от забоя выработки, вертикальная нагрузка на нее снижается в 1,54 раза.</p>

        <p>In-situ testing technique of temporary support is given. The values of stress and normal force in arch and sides of steel support are shown. Determination of vertical load magnitude is done. It was determined that vertical load on support decreases by 1,54 times, if lag of support installation from the face is16 m.</p>
