Non-Rotational Drilling and Sampling in Frozen Soils, While this does not meet the strict definition of drilling, it does achieve the same result—a borehole. Non-rotational drilling tools do not remove cuttings from the hole, and deepening occurs due to compression of soil, bailing, and/or removal of core samples. This chapter describes the various po

Air and Foam Drilling in Frozen Soils,friendly than drilling with a fluid. Compressed air does not freeze when drilling in permafrost, does not filter liquid into frozen soil pores, and has a low specific-heat capacity. Of the variety of circulation mediums, chilled air and foam are the best ones from the standpoint of preventing permaf
