Product Detail
Product用途:
Applicable to projects related to geological hazard assessment and mitigation, as well as engineering investigation and design; also applicable in the fields of mineral resource exploration, engineering geological surveys, and hydrogeological studies. The specific categories are as follows:
◆ Mineral resource exploration: locating metallic ore bodies, hydrocarbon structures, or coal seams; identifying mineralization zones, etc.
◆ Engineering geological investigation: detecting karst features, faults, underground rivers, and other subsurface hazards; assessing the stability of tunnels and dam foundations.
◆ Hydrogeological studies: delineating aquifers and groundwater flow paths, or monitoring the dispersion of contaminant plumes.
◆ Archaeology and glacial research: uncovering buried relics (such as ancient tombs or city walls) or measuring glacier thickness and subglacial topography.
◆ Disaster Early Warning: Assessing the structural integrity of landslide masses and the risk of subsidence in mined-out areas.

Case Study:
Detection Project: Non‑shielded ground‑penetrating radar survey at a coal mine in Shizuishan City;
Detection requirements: Conduct detection 12.5 meters above the main shaft entrance of the coal mine; (following on-site discussions with mine personnel, the survey line is positioned directly above the projection of the main shaft).
Site description: This is the CAD plan of the main and auxiliary inclined shafts at the Baijigou Coal Mine. The main shaft extends downward from the surface at a dip angle of 16°, with a length of approximately 300 meters and a vertical rise of about 100 meters. The current survey was conducted in the direction from the shaft bottom toward the shaft mouth. The overburden above the main shaft consists of bedrock.
12.5 m detection area above the main shaft;
A 12.5-m resolution was used for the survey, with a total line length of 63 m and a point spacing of 0.5 m.
Data Image:
Data description: Analysis of the data reveals that the yellow‑highlighted area exhibits a continuous in-phase axis, with a distinct secondary radar signal. Combined with field observations, this location is preliminarily identified as the reflection signal from the main shaft entrance. The starting depth is 24.46 m; at the junction between the mountain and the flat terrain, the depth is 43.43 m; and the ending depth is 67.53 m. The elevation difference along the horizontal plane is 18.97 m, yielding an inclination angle of 17° for this radar’s in-phase axis.
