      <abstract xml:lang="ru">
        <p>Трещиноватость имеет существенное значение при оценке прочностных и других физико-механических свойств пород, добываемых в качестве бутового камня, для производства щебня, я также при ведении на карьерах буровзрывных работ. Однако почти единственным пособием по изучению тре­щиноватости пород месторождений строительного камня яв­ляется брошюра Б. П. Беликова, рассматривающая в основ­ном только месторождения блочного камня.</p>

        <p>Fracturing is essential in assessing the strength and other physical and mechanical properties of rocks extracted as rubble stone, for the production of crushed stone, as well as in the conduct of drilling and blasting operations in quarries. However, almost the only manual on the study of fracturing of rocks of building stone deposits is a brochure by B. P. Belikov, considering mainly only deposits of block stone .</p>
