        <p>В настоящее время промышленность Советского Союза серийно выпу­скает врубовые машины только типа «Урал-33», которые применяют на тех шахтах, где нельзя использовать комбайны. При существующей технологии добычи сланцев подрубку производят у почвы пласта (по третьему слою сланца) машиной «Урал-33» с двухметровым баром, с полезной глубиной вруба 1,9 м ...</p>

        <p>At present the industry of the Soviet Union mass-produces only Ural-33 type punching machines, which are used in those mines, where it is impossible to use harvesters. With the existing technology of oil shale mining, the undercutting is made at the bed soil (on the third layer of oil shale) by the machine “Ural-33” with a two-meter bar, with a useful furrow of 1.9 m ...</p>
