      <abstract xml:lang="ru">
        <p>Месторождение горючих сланцев Эстонии характеризуется большими притоками воды, достигающими в весенний паводок 6000—8000 м3 / час (например, на шахте Кява II в апреле 1955 г.). Геодезическая высота подъема воды невелика: 20—40 м — для главного водоотлива и 3— 4,5 м — для участковых перекачных.</p>

        <p>The Estonian oil shale deposit is characterized by large water inflows reaching 6000-8000 m3 / hour in spring floods (e.g. at the Käva II mine in April 1955). The geodetic height of water rise is small: 20-40 m - for the main drainage and 3- 4,5 m - for the area pumping.</p>
