Near-surface seismic refraction applied to exploring subsurface clay layer at a new mining area in southeast Cairo, Egypt

Abstract

A near-surface seismic refraction survey was conducted at a new mining area located in southeast Cairo, Egypt, to explore the subsurface clay layer for future economic use in mining and cement industry. The purpose of the survey has been to provide geological and geophysical information because no borehole was existent in the area under investigation. The aim of study had been to explain the main characteristics of the subsurface layers. For this purpose, a new technique has been used to acquire and process the data. This technique provides critical information to determine the depth of the subsurface layers, as well as morphology, stratigraphy, and potential locations of the clay layer for future economic use. The thickness and general shape of the clay layer in the whole area were determined and are illustrated in maps.

Determination of engineering properties of granodiorites at Deriner dam site by using seismic refraction method (Artvin)

“…Sismik hızlar Poisson oranı ve diğer elastik parametreler gibi ana mekanik özelliklere bağlı olarak değiştiğinden kaya ve toprak kütlelerinin özelliklerinin tanımlanmasında son derece kullanışlıdır ve özellikle sondaj çalışmalarının çok zor olduğu masif kayalar hakkında sismik hızlar sayesinde önemli bilgiler elde edilir [6]. Bu kapsamda, yöntem güncel olarak, köprü, tünel, baraj, metro, nükleer santraller ve diğer önemli devasa tesisler gibi yapıların inşaasından önce kaya kalitesinin belirlenmesinde ve zayıf kayanın varlığının araştırılmasında en uygun yöntemdir [7]- [13].…”

Velocity Measurements of Powdered Rock at Low Confining Pressures and Comparison to Lunar Shallow Seismic Velocity

“…While historically the seismic studies of extraterrestrial bodies have focused on body‐wide or large features (kilometer depth scale), less work has focused on the near‐surface seismic properties of these bodies (meter depth scale). Near‐surface seismic studies are regularly employed on Earth for geohazard detection, site characterization, and resource exploration (e.g., Abd El‐Aal & Mohamed, 2010; Gálfi & Pálos, 1970; Hack, 2000; McCann & Forster, 1990; Pegah & Liu, 2016; Steeples, 1990) and may be a viable technique for similar studies on extraterrestrial bodies. With the increase in lunar exploration activity associated with the Artemis program, which may place humans on the Moon as early as 2026, increasing our understanding of the Moon's near‐surface in terms of geotechnical safety and resource potential will be paramount for sustainable space development (Metzger, 2016; Spudis & Lavoie, 2011).…”

Seismic refraction study of Gurara dam phase II, northwestern Nigeria

“…The seismic refraction method has been successfully utilized in areas where drilling has proved difficult due to the presence of massive pebbles to obtain results giving both depth to and quality of hard rock in terms of seismic velocity vis-à-vis strength (Rao et al, 2004). From the engineering vantage point, shallow seismic refraction has been used to study bedrock foundation properties in road tunnelling, dam sites, quarries, hydroelectric power plants, subway constructions, nuclear power plants and many other facilities (Abd El-Aal and Mohamed, 2010).…”
