      <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 excavation area depends on the operation of mining machines, atmospheric pressure fluctuations, collapse of rocks of the main roof, irregularity of air supply, etc. Regardless of the influence of these factors, the methane content in the outgoing jet of the site should not exceed 1%. Consequently, it is necessary to supply to the site such amount of air Qpred that would ensure compliance with the requirements of Safety Rules at any combinations of these factors.</p>
