        <p>Расслаиваемость слоистой кровли камер существенно уменьшает изгибную жесткость слоев, что приводит к значительному увеличению прогибов нижних слоев кровли и формированию предельных зон.</p>

        <p>The delamination of layered chamber roofs significantly reduces the bending stiffness of the layers, which leads to a significant increase in the deflections of the lower layers of the roof and the formation of limit zones.</p>
