Book Description
Research has been in progress since July 1970 to determine which geophysical and remote-sensing methods offer the most promising results for detecting subsurface cavities and what might be done to further develop them. Through extensive field tests, it has been determined that none of the standard electrical resistivity procedures give consistently good results. As a result of the initial field testing, a new process of data interpretation has been developed for one specific electrode configuration. Cavities less than 10 feet in diameter and at the depths greater than 100 feet were located. Research is continuing to adapt this process for locating water- or mud-filled cavities.

Detection of Subsurface Cavities by Surface Remote Sensing Techniques
Author: L. S. Fountain

ISBN:
Category : Electromagnetic measurements
Languages : en
Pages : 140
Book Description
The research is part of a program underway to evaluate remote sensing instrumentation and methods for locating subsurface cavities that can cause serious highway construction and maintenance problems. Three methods of subsurface cavity detection based on different geophysical techniques were experimentally evaluated, including ground-penetrating radar, gravity profiling, and earth resistivity profiling. Tests were conducted at three sites having different geological environments. Verification tests showed all methods to be capable of locating air-filled cavities.

Handbook of Geophysical Cavity-locating Techniques with Emphasis on Electrical Resistivity
Author: Keith G. Kirk
Publisher:
ISBN:
Category : Caves
Languages : en
Pages : 192
Book Description
This handbook is primarily a description of the methodology of using earth resistivity techniques for locating cavities. Only a small portion of the handbook will be devoted to the theoretical considerations behind these techniques. However, the annotated bibliography cites ample literature to satisfy the needs of the theoretician. Along with earth resistivity techniques, several geophysical techniques will be examined in lesser detail with respect to cavity location. Micro-gravity, high-resolution seismic reflection profiling, and ground probing radar were selected because they show good success rates in cavity detection. High-resolution seismic profiling shows particularly good promise as an effective tool in cavity location. Techniques in photo interpretation will also be discussed with regard to possible cavity location.

Category : Technology & Engineering
Languages : en
Pages : 154
Book Description
This book is based on the contributions of several authors and attempts to describe the roles human activities play in causing geohazards either directly or indirectly through man-made climate change. The risk of these man-made geohazards and the risk assessment are also discussed in this book. Each chapter keeps the authors' notations that vary from chapter to chapter. These authors' notations have been maintained to reduce unintended confusion and errors. Readers should be aware of this variation.

ISBN: 9780853342168
Category : Science
Languages : en
Pages : 284
Book Description
"The first phase of geophysical exploration is carried out on the subsurface.The subsurface in this phase is inaccessible to direct observation. D.W. Strangway presents an interesting and effective method: audiofrequency magnetotelluric (AMT) sounding. In the second phase where observations can be made, D.J Buchanan writes of fault detection in coal seams, and A. Hussain writes about of gravity surveys.Other contributions include, improvement of geophysical logs by filtering and a troublesome problem which can appear in either phase of exploration-discovery and exploration of caves and abandoned mine workings.'
