      <abstract xml:lang="ru">
        <p>Метановыделение в пределах выемочного участка зависит от работы добычных машин, колебаний атмосферного давления, обрушения горных пород основной кровли, неравномерности подачи воздуха и т. д. Независимо от влияния этих факторов, содержание метана на исходящей струе участка не должно превышать 1%. Следовательно, на участок необходимо подавать такое количество воздуха Qpaсч которое обеспечивало бы соблюдение требований Правил безопасности при любых комбинациях указанных факторов.</p>

      <abstract xml:lang="en">
        <p>Methane emission within the extraction panel depends on the operation of mining machines, atmospheric pressure fluctuations, collapse of the main roof rocks, non‑uniformity of air supply, etc. Regardless of the influence of these factors, the methane content in the outgoing air stream of the panel should not exceed 1%. Consequently, it is necessary to supply to the panel such amount of air Qcalc that would ensure compliance with the requirements of the Safety Rules for any combinations of these factors.</p>
