      <abstract xml:lang="ru">
        <p>В горной промышленности, особенно при строительстве гидротехни­ческих сооружений, проходятся выработки сечением 50-80 м2 при значительной протяженности. Для проветривания таких выработок по вентиляционным трубам в забой должен подаваться большой объем свежего воздуха. Иногда это практически трудно осуществимо, так как вентиляционные трубы обладают большим сопротивлением и допускают значительные утечки.</p>

        <p>In the mining industry, especially during the construction of hydraulic engineering structures, workings with a cross-section of 50–80 m² are driven over considerable lengths. To ventilate such workings, a large volume of fresh air must be supplied to the face through ventilation pipes. Sometimes this is practically difficult to achieve, since ventilation pipes have high resistance and allow significant leaks.</p>
