Electromagnetic Pulse Sounding for Geological Surveying with Application in Rock Mechanics and Rapid Excavation Program
نویسنده
چکیده
Progress toward the development of an electromagnetic pulse sounding probe for the detection and delineation of geological anomalies, primarily in a hard rock medium, is reported. This report covers research performed on Contract H0210042 during the period 24 February 1971 to 23 February 1972. Analytical studies on design data for the probe and on the scattering by planar and spherical contrasts are summarized. Successful measurements made using a "first generation" version of the probe on conducting and dielectric cylindrical targets in a lossy overburden and'on specific anomalies in a limestone medium are reported.

Analysis of support pressure for stabilization of rock blocks in the Zaker tunnel
This paper presents the results of engineering geological studies of rock blocks along a road tunnel in NW Iran. The tunnel is to cross the Western Alborz Mountain Range through 530 m in length with 11.2 m span and 8 m height. Eocene tuffs and andesites crop out in whole of the tunnel route. Numerical analyses are done using, a 3D stability analysis and visualization program, called Unwedge tha...
متن کاملApplication of Schmidt rebound number for estimating rock strength under specific geological conditions
A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. This is attributed to the fact that in most cases one formula is used for all types of rocks, altho...

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. The electromagnetic tomography is a new geophysical technique in the tunnel. This method has advantages such as high resolution, high reliability...
متن کاملA state-of-the-art review of mechanical rock excavation technologies
The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...
متن کاملFRACOD Modeling of Rock Fracturing and Permeability Change in Excavation Damaged Zones
Characterization of Excavation Damaged Zone (EDZ) around an underground excavation is a major research topic for deep geological disposal of medium to high level radioactive waste. Rock fracturing due to excavation and thermal loading and its resultant rock mass permeability change in the EDZ are important aspects in the EDZ characterisation. A new function to predict rock mass permeability cha...
