      <abstract xml:lang="ru">
        <p>Современное развитие механики горных пород выдвинуло важную задачу изучения влияния скорости деформации на свойства пород. Исследо­вание процессов разрушения пород при динамических нагрузках имеет большое значение для совершенствования технологии добычи полезных ископаемых. Механические свойства при динамическом нагружении важно знать при конструировании горных машин, бурении скважин на больших скоростях, разрушении пород взрывом.</p>

        <p>The modern development of rock mechanics has put forward the important task of studying the effect of strain rate on rock properties. The study of rock fracture processes under dynamic loading is of great importance for the improvement of mining technology. Mechanical properties under dynamic loading is important to know when designing mining machines, drilling wells at high speeds, destruction of rocks by explosion.</p>
