      <abstract xml:lang="ru">
        <p>Метод расчета основывается на том, что размеры очистной камеры определяются предельной устойчивостью кровли после окончания очист­ных работ в камере. Следовательно, система и последовательность отработки камеры не влияют на предлагаемый метод расчета.</p>

      <abstract xml:lang="en">
        <p>The method of calculation is based on the fact that the size of the cleaning chamber is determined by the ultimate stability of the roof after the end of cleaning work in the chamber. Consequently, the system and sequence of chamber mining do not affect the proposed method of calculation.</p>
