      <abstract xml:lang="ru">
        <p>Исходными параметрами при решении задач, связанных с проявле­ниями горного давления, являются показатели прочности горных пород. Основным из них служит предел прочности при сжатии. Как правило, он определяется в лаборатории на образцах исследуемых пород. Известны и производственные методы, позволяющие определять пре­дел прочности непосредственно на поверхности обнажения пород (забое, стенке выработки, кровле) или на некотором расстоянии от контура вы­работки, в скважине. Однако эти методы несовершенны, трудоемки и сложны ...</p>

      <abstract xml:lang="en">
        <p>The initial parameters in solving problems related to the manifestations of rock pressure are rock strength indicators. The main of them is the compressive strength. As a rule, it is determined in the laboratory on samples of the rocks under study. There are also known production methods that allow to determine the ultimate strength directly on the surface of rock outcrop (face, wall of excavation, roof) or at some distance from the contour of excavation, in a borehole. However, these methods are imperfect, labor-intensive and complex ...</p>
