YDT-175
Xi'an
Product Description
[Range of Application]
Pit prospecting technology can look for and select various targets by researching the propagation characteristics of electromagnetic wave between holes or underground tunnels and the dielectric absorption situation. It has good exploration effect on collapse columns, faults, folds and thin coal areas and other abnormal geology in the working face, which can guide the exploition of coal mine. According to the automatic identification of abnormality by measurement data, it can quickly realize the two-dimensional attenuation by absorption in the working face.Detect the fault with a drop of more than one third of the thickness of the coal bed; detect the general range of the water-heavy area; detect fluctuation variation situation of the roof and floor of the coal bed; detect the collapse column with a diameter of more than 15m; igneous rock intrusion; change zone of the thickness of the interlayer.
