      <abstract xml:lang="ru">
        <p>Современные шарошечные станки для бурения скважин с поверхности спо­собны бурить вертикальные или наклонные скважины диаметром до 320 мм и глубиной до 30 м. При подземной разработке месторождений используются скважины, пробуренные под любым углом к горизонту, а станки для их буре­ния обеспечивают проходку скважин диаметром до 105 мм и длиной не более 100 м.</p>

        <p>Modern cone drilling machines for drilling wells from the surface are capable of drilling vertical or inclined wells up to 320 mm in diameter and up to 30 m deep. In the underground development of deposits are used wells drilled at any angle to the horizon, and machines for their drilling provide penetration of wells with a diameter of up to 105 mm and a length of no more than 100 m.</p>
