      <abstract xml:lang="ru">
        <p>Рассмотрены особенности аварийных обрушений основной кровли при слоевой выемке Третьего калийного пласта. Проведен предварительный анализ горно-геологических условий их проявлений. Выявлены параметры непосредственной кровли, оказывающие влияние на интенсивность обрушения. С помощью критерия Фишера найден "критерий динамичности", позволяющий оценить опасность различных участков шахтного поля.</p>

        <p>The peculiarities of emergency collapses of the main roof during layer excavation of the Third potash layer were considered. Preliminary analysis of mining and geological conditions of their occurrence was carried out. The parameters of the immediate roof influencing the collapse intensity were revealed. Using Fisher's criterion, a "dynamism criterion" was found to assess the danger of different parts of the mine field.</p>
