“…Specifically, it has been used to survey for uncharted mine galleries (Maillol et al, 1999) and subsurface cavities (van Schoor, 2002). For our surveys, an automated 8-channel AGI SuperSting R8 IP system was used to collect resistivity data at each site on a 50 × 50 m grid with electrode spacings of 1 m. A dipole-dipole configuration, with 'a-spacings' of 1, 2, and 3 m and 'n-levels' of 1 to 8 (Parasnis, 1997), was used for each survey line on both sites.…”

We present a comparison of the abilities of Electrical Resistivity Tomography (ERT) and Self-Potential Tomography (SPT) to detect and characterize buried mineshafts at the site of a former colliery. Surface electrical resistivity and self-potential (SP) surveys were carried out at two test sites, each containing a hidden shaft. The ERT survey results indicate that both sites had a highly heterogeneous subsurface resistivity distribution, which we attribute to colliery spoil and former infrastructure. ERT managed to distinguish an air-filled, highly resistive mineshaft from this background, but failed to detect the second shaft, which was backfilled and therefore had a much lower resistivity contrast with the surrounding formation. However, SPT located both shafts, gave an indication of their size, shape and depth of burial, and was able to distinguish the openfrom the backfilled mineshaft due to the strength of the associated SP anomalies. We argue that these SP anomalies are likely to be due to changes in the streaming potential caused by preferential drainage into the shafts.

“…Empty voids are assumed to be very high resistive bodies; so they are indicated as high resistivity anomalous zones in electrical resistivity inversion images [23]. Our intention is to detect the cavities, their geometry, and the depth of occurrences as well as the surrounding media geological properties.…”

This paper is devoted to the application of the Combined Resistivity Sounding and Profiling electrode configuration (CRSP) to detect underground cavities. Electrical resistivity surveying is among the most favorite geophysical methods due to its nondestructive and economical properties in a wide range of geosciences. Several types of the electrode arrays are applied to detect different certain objectives. In one hand, the electrode array plays an important role in determination of output resolution and depth of investigations in all resistivity surveys. On the other hand, they have their own merits and demerits in terms of depth of investigations, signal strength, and sensitivity to resistivity variations. In this article several synthetic models, simulating different conditions of cavity occurrence, were used to examine the responses of some conventional electrode arrays and also CRSP array. The results showed that CRSP electrode configuration can detect the desired objectives with a higher resolution rather than some other types of arrays. Also a field case study was discussed in which electrical resistivity approach was conducted in Abshenasan expressway (Tehran, Iran) U-turn bridge site for detecting potential cavities and/or filling loose materials. The results led to detect an aqueduct tunnel passing beneath the study area.

Non-destructive test which refers to electrical resistivity method is recently popular in engineering Ujian tak musnah yang merujuk kepada kaedah kerintangan elektrik semakin banyak digunakan dalam kajian kejuruteraan, alam sekitar, arkeologi dan perlombongan. Berdasarkan kajian terdahulu, interpretasi keputusan kerintangan elektrik sering diperdebatkan disebabkan kekurangan bukti kajian dalam perspektif kuantitatif. Kebiasaannya interpretasi keputusan kerintangan elektrik banyak bergantung kepada perspektif kualitatif justeru berkemungkinan besar berisiko tinggi untuk menghasilkan keputusan yang salah. Maka, kajian ini telah menjalankan uji kaji makmal kerintangan elektrik tanah disokong oleh uji kaji sifat asas fizikal tanah seperti uji kaji taburan saiz zarah (d), kandungan lembapan (w), ketumpatan (ρ bulk ) dan had Atterberg (LL, PL dan PI). Uji kaji dijalankan untuk menghasilkan satu siri nilai kerintangan elektrik (ERV) berdasarkan kuantiti air yang berbeza terhadap lempung berkelodak dan kelodak berpasir dalam keadaan longgar dan juga mampat. Hasil keputusan menunjukkan nilai kerintangan tanah adalah berbeza dalam keadaan longgar (L) dan mampat (C) serta variasi kandungan air dan juga ketumpatan (pasir berkelodak = ERV = 638.8ρ -0.418 , w (D) = 1397.1ρ -0.574
