The deployment of China's first helicopter borne electromagnetic detection system is of great significance.
I. Technical innovation and exploration ability
1. Advanced detection technology
This system combines the mobility of helicopters with electromagnetic detection technology. Electromagnetic detection can help in exploring underground geological structures, mineral resources, and groundwater resources. By being helicopter borne, it can cover a large area more quickly compared to traditional ground based electromagnetic detection methods.
It has high precision sensors that can detect weak electromagnetic signals from the subsurface. These sensors are able to capture detailed information about the resistivity and conductivity of the underground medium, which is crucial for accurately mapping geological formations.
2. Enhanced exploration efficiency
Helicopters can reach remote and difficult to access areas, such as mountainous regions, forests, and wetlands. This expands the scope of electromagnetic exploration and enables the discovery of potential resources in areas that were previously difficult to survey.
The system can perform continuous detection during flight, greatly reducing the time required for large scale exploration. For example, in a large scale mining exploration project, it can quickly scan a vast area to identify potential ore bearing zones, which is much more efficient than the piecemeal exploration of ground based methods.
II. Application in resource exploration and geological research
1. Mineral resource exploration
It is very useful for finding metal minerals such as copper, gold, and iron. Different minerals have different electrical properties, and the electromagnetic detection system can detect the abnormal electromagnetic response caused by the presence of these minerals underground. For instance, in a copper rich area, the system can detect the characteristic electromagnetic signals associated with copper deposits through the analysis of the measured data.
2. Groundwater exploration
Groundwater has a different resistivity compared to the surrounding rock formations. The helicopter borne electromagnetic detection system can map the distribution of groundwater by detecting these resistivity differences. This is important for areas facing water shortages, as it can help in locating potential groundwater sources more accurately and quickly, providing valuable information for water resource management and development.
3. Geological structure research
By detecting the electromagnetic properties of the subsurface, it can help in understanding geological structures such as faults, folds, and strata boundaries. This information is essential for geological research, earthquake prediction, and engineering geological evaluation. For example, in earthquake prone areas, mapping the subsurface geological structures can help in assessing the potential seismic risks and providing a scientific basis for urban planning and infrastructure construction.
