      <abstract xml:lang="ru">
        <p>Ручной труд в производстве геологоразведочных и инженерно-гео­логических исследований все еще занимает большое место. Среди этих работ не малое значение имеет ручное бурение шпуров при проведении разведочных выработок. Производительность труда при ручном бурении невысока. Так, для проходки шпура глубиной 1,5 м и диаметром 35 мм в породах средней крепости затрачивается 3,14 человеко-часа. Примене­ние же существующих механизмов для бурения шпуров при проведении разведочных выработок в ряде случаев оказывается невозможным из-за: отсутствия источников энергии. Большой объем., трудоемкость и высокая стоимость ручного бурения настоятельно требуют механизации этого процесса.</p>

        <p>Manual labor in the production of exploration and engineering-geological research still occupies a large place. Among these works, manual drilling of boreholes in the exploration workings is of no small importance. Labor productivity in manual drilling is low. For example, for sinking a borehole depth of 1.5 meters and a diameter of 35 mm in rocks of medium strength is spent 3.14 man-hours. The use of existing mechanisms for borehole drilling in exploratory excavations in some cases is impossible due to the lack of energy sources. Large volume, labor intensity and high cost of manual drilling urgently require mechanization of this process.</p>
