      <abstract xml:lang="ru">
        <p>Для обеспечения очистных и подготовительных забоев достаточным количеством воздуха необходимо правильно определить потери воздуха как на действующих шахтах, так и при их проектировании. Во многих шахтах Донбасса, как и других угольных бассейнах страны, значительный удельный вес (нередко достигающий 50—70%) в общешахтных подземных утечках приходится на потери воздуха в па­раллельных выработках.</p>

        <p>In order to provide cleaning and preparation faces with sufficient amount of air it is necessary to correctly determine air losses both at operating mines and at their design. In many mines of Donbass, as well as in other coal basins of the country, a significant specific weight (often reaching 50-70%) in the general mine underground leakages falls on air losses in parallel workings.</p>
