“…The CRSP array provides an enhanced lateral and in depth coverage, due to the acquisition of more data in a section (Figure 1). In practice, CRSP has been successfully applied to different mineral exploration and engineering site investigations [18,25,26], and [27]. It should be noted that a combined method, called "Combined Sounding-Profiling Resistivity" was also proposed by [28].…”

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.

“…Regarding the mentioned factors and problems, Ramazi and Mostafaei in the 2012 tried to design a new array, which reduces some of the mentioned problems, provides a good image of the subsurface, and can be used practically in the field, especially for one channel measurement systems. The designed array is called combined resistivity sounding and profiling or CRCP (Ramazi and Mostafaei ; Mostafaei and Ramazi ). CRSP is a combination of geoelectrical profiling and sounding, as illustrated in Fig.…”

The main issue in mineral exploration is to obtain as much information as possible in a time‐ and cost‐efficient manner. This may be achieved through a combination of geophysical methods including the induced polarization method. The induced polarization is the most applicable method in case of metal exploration through drilling. We argue that the relationship between induced polarization, electrical resistivity and ore grade data may be used in resource estimation. This argument is tested in the active copper mine of Madan Bozorg, Abassabad, which is located in the Miami‐Sabzevar mineralization belt in NW Iran. Within the borehole locations, geophysical profiles of induced polarization and electrical resistivity were designed and surveyed using combined resistivity sounding and profiling array. Two‐dimensional models of induced polarization and electrical resistivity were prepared through inversion of geophysical data, after the primary processing. The three‐dimensional block models of induced polarization and electrical resistivity were also compiled using geostatistical methods. Obtained two‐dimensional and three‐dimensional models of induced polarization and electrical resistivity were checked using exploratory boreholes to investigate the relationship among induced polarization, electrical resistivity and copper grade. The three‐dimensional block model of the copper ore was prepared using cokriging and artificial neural network, using a combination of induced polarization and drilling data. In the cases where borehole data were unavailable, the presence of copper ore was predicted by artificial neural network and cokriging methods, and the three‐dimensional models of ore body were constructed in all of the study area. Obtained models based on the predicted copper ore distribution were checked and compared with ore distribution model compiled using drilling data. The results indicate a good agreement between predicted and real results. This led to reduction of borehole number to about 45% and the optimization of boreholes locations. Finally, an optimized drilling plan has been prepared and presented for the Abassabad copper mine.

“…As seen in Figure 5, the CRSP array has the advantage of penetrating deep in the subsurface as well as detecting lateral changes through the acquisition of more data in a section. In practice, CRSP has been successfully applied to different mineral exploration and engineering site investigations (Ramazi and Mostafaie, 2013). It should be noted that a combined method, called 'combined sounding-profiling resistivity' was also proposed by Karous and Pernu (1985).…”
