Available in PDF, EPUB and Kindle. Book excerpt: An expensive drill has been modified to provide researchers with the ability to auger an open hole or to acquire continuous, undisturbed 76-mm-diam core samples of a variety of perennially frozen materials that are suitable for chemical and petrographic analysis. It was developed by field testing in support of research from 1980 to 1983. Operation of the drill is based mainly on using a minimum of power to cut through frozen ground with tungsten carbide cutters on a CRREL coring auger. The ice content, temperature and grain size of the frozen sediments are important variables determining the sampling depth. Perennially frozen sediments with temperatures in the range of -0.5 C to -8.5 C have been continuously cored with this drill. Drilling and sampling are most efficiently conducted when ambient air temperatures are below freezing and the active layer is frozen. The self-contained lightweight drill is readily transportable off-road by helicopter or tracked vehicle, or by towing over roads. It is locally self-mobile by use of a winch. Total cost of the drill and modifications is estimated at approximately $10,000.

Book Synopsis Preparation and Description of a Research Geophysical Borehole Site Containing Massive Ground Ice Near Fairbanks, Alaska by : Allan J. Delaney
Download or read book Preparation and Description of a Research Geophysical Borehole Site Containing Massive Ground Ice Near Fairbanks, Alaska written by Allan J. Delaney and published by . This book was released on 1987 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A geophysical control site consisting of 27 holes drilled in permafrost and cased with ABS pipe has been completed near the USACRREL permafrost tunnel at Fox, Alaska. The site provides excellent control on a range of material types in permafrost terrain including frozen silt, gravel, bedrock, and all common ground-ice types such as wedge, lens, and pore ice. The holes delineate massive ground-ice features of which there is no surface manifestation. Ground temperature data is available from a small-diameter glycol-filled hole. This report describes the site, its preparation, and the soil logs and data obtained. Keywords: Drilling equipment; Ground-ice; Ground temperature.
Book Synopsis Geotechnical and Exploration Drilling in the Polar Regions by : Pavel G. Talalay
Download or read book Geotechnical and Exploration Drilling in the Polar Regions written by Pavel G. Talalay and published by Springer Nature. This book was released on 2023-01-01 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of drilling technologies in the polar regions, from the portable drilling equipment for shallow sampling and coring, to heavy drilling equipment for deep onshore and offshore drilling. Particular attention is given to safe drilling methods in permafrost. In recent years, interest in drilling in the polar regions has increased under the pressure of the geopolitical “rush” and the undiscovered resource potential. In addition, borehole monitoring of permafrost thermal states is urgently needed to obtain evidence of climate change. The book focuses on the latest drilling technologies but also discusses the historical development of sampling, and drilling tools and devices, over the last 60–70 years providing valuable insights into a way forward and future possibilities.

Book Synopsis An Investigation of Core Drilling in Perennially Frozen Gravels and Rock by : G. Robert Lange
Download or read book An Investigation of Core Drilling in Perennially Frozen Gravels and Rock written by G. Robert Lange and published by . This book was released on 1973 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problems of obtaining frozen samples by core drilling of perennially frozen gravel and rock were investigated. Most of the core drilling was carried out in ice-bonded, well-graded alluvial gravel with the ground temperature near its freezing point. Both chilled compressed air and oil-based liquids were used as drilling fluids. The details of both successful and unsuccessful coring attempts are reported and related to descriptions and photographs of samples of a wide range of quality. Drilling variables such as weight on the bit, rotational velocity, rate of penetration, fluid temperatures, viscosities, flow rates and pressures and mechanical details of the diamond bits are reported. (Modified author abstract).
