      <abstract xml:lang="ru">
        <p>На основе градиентного подхода разрабатываются критерии образования сдвиговых трещин и трещин отрыва при сжатии в условиях концентрации напряжений вблизи горных выработок. С учетом масштабного эффекта определен вид функции локальной прочности, получены выражения для критического давления, проведено сопоставление результатов расчета с экспериментальными данными.</p>

      <abstract xml:lang="en">
        <p>Using the gradient approach the criteria of shear and tensile cracking are developed in compression under conditions of stress concentrations near mine workings. Considering the size effect, a function type of local strength is determined, expressions for critical pressure are derived and comparison between analytical and experimental data is performed.</p>
