      <abstract xml:lang="ru">
        <p>Одним из перспективных направлений разработки и совершенствования но­вых способов бурения является разрушение горных пород путем их плавления или испарения в условиях интенсивного теплового воздействия в зоне забоя скважины. Эффективность бурения-плавления мало зависит от твердости и плас­тичности горных пород, а также от внешних факторов, и в этом смысле облада­ет известной универсальностью, что позволяет уже в настоящее время предви­деть его преимущества перед механическим бурением в отдельных специфичес­ких условиях проходки скважин ...</p>

      <abstract xml:lang="en">
        <p>One of the promising directions for the development and improvement of new drilling methods is the destruction of rocks by melting or vaporizing them under conditions of intense thermal influence in the bottom-hole zone. The efficiency of drilling-melting depends little on the hardness and plasticity of rocks, as well as on external factors, and in this sense has a certain universality, which allows already now to anticipate its advantages over mechanical drilling in some specific conditions of well sinking ...</p>
