CUGTEM-GK1 engineering survey of TEM

Application Profile
The instrument will be used mainly for the shallow (5 M-300M depth range) of geological prospecting and shallow water, prospecting work. In particular is expected to underground mining, mining tunnels and highway, railway, tunnel boring geological conditions before the end detection To prevent cave-in advance of landslides, flooding and other disasters occur, and ensure the safety of construction, to avoid huge economic losses.
The characteristics of electromagnetic -
Using the latest 32-bit microcontroller series of low-power ARM core as a controller, using one-button operation, a high degree of automation;
Use of reflective liquid crystal display screen, very low power consumption, can work in direct sunlight, especially in the field open to the working environment;
Used to replace large-capacity disk drives to the electronic memory, in the wild-vibration transport environment, the more assurance of safety equipment;
Launched a small current, and high-density, high sensitivity of the data collection method is more suitable for shallow geological exploration;
With a GPS satellite positioning systems, more convenient for field work;
Accept the use of ultra low-noise pre-amplifier, data collection can arbitrarily choose the appropriate number of superimposed, to ensure the accuracy and wide dynamic;
Advanced interpretation software system: the ground work, including the half-space to explain software systems and underground (underground roadway, tunnel, military engineering, etc.) work space to explain the entire software system.
The main purpose
Shallow (Mass Transit 5 M-300M) engineering geology, hydrogeology and environmental geological exploration;
Underground tunneling project before exploration and geological conditions, geological disaster prediction;
Coal mined-out (collapse), karst areas and air defense projects, such as the geological survey;
Gobi desert, arid region and the surface layer of volcanic rock, such as high resistance and the coverage area of rivers, lake, wetlands, such as salinity beach low resistance of the surface area coverage, such as not suitable for traditional DC law work on the ground, carried out underground mineral resources, water and Geological prospecting conditions;
Metals and non-metallic mineral resources prospecting;
Mountain terrain and poor conditions in the local geological exploration.
