      <abstract xml:lang="ru">
        <p>Расчет шахтных воздухопроводов аналитическими и графоаналитическими способами сводится в основном к определению двух величин: 1) утечек воздуха или доставочного коэффициента μ; 2) напора h, который необходимо создать, чтобы к концу става труб поступало заданное количество воздуха Qзaб. Предложено много формул для подсчета этих величин. А. И. Швырков на основании теоретических ис­следований движения воздуха в воздухопроницаемых трубопроводах установил функциональную зависимость между величинами.</p>
