Engineering exploration
2024-02-24
The purpose of this survey was to use the ZZ Universal resistivity meter to explore possible geological reasons as part of a railway tunnel (from 370 to 430m) experienced settlement after completion. A total of 63 electrodes were laid on the surface above the tunnel and one was placed into the tu... -
Dam safety inspection
2024-02-22
The purpose of the dam safety inspection was to monitor the safety of a stone masonry overflow dam (12m high and 161m long) using the ZZ Universal resistivity meter. -
Mineralisation exploration
2024-02-22
For this survey, several crosshole sections were undertaken in order to deduce the developing direction and size of the underground mineralisation. -
Surface survey
2020-04-13
The purpose of this surface resistivity survey was to delineate the development direction of a gold ore deposit. The surface resistivity survey uses a 10m interval cable, which enables the ZZ Universal system to detect an explorable depth of up to 120m. The system found a low resistive band from ... -
Surface borehole survey
2020-04-13
These two surveys were designed to maximise the value of two existing boreholes. There was already known mineralisation existing between 60-80m in Figure 1 and 100-115m in Figure 2. The inversion resistivity images showed not only the shape of ore bodies, but also other possible high mineralisati... -
Crosshole survey
2020-04-13
Crosshole surveys are used when two or more boreholes are present in order to provide the maximum imaging accuracy for the cross-section between respective boreholes. -
Surface-points survey
2020-04-13
Surface-point resistivity surveys are used to obtain detailed survey information around a known anomaly. At least one borehole is required near the point of interest. -
Highly efficient Mise a la Masse
2020-04-13
The traditional Mise-a-la-masse method is very useful for finding the developing direction of the ore body. However, this method is very time and effort-consuming.
