      <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>

        <p>Calculation of mine air ducts by analytical and graphoanalytical methods is mainly reduced to the determination of two quantities: 1) air leakage or the delivery coefficient μ; 2) the head h, which must be provided so that a given amount of air Qzab reaches the end of the stack of pipes. Many formulas for calculating these values have been proposed. A. I. Shvyrkov, on the basis of theoretical studies of air movement in air‑permeable pipelines, established a functional dependence between these quantities.</p>
