【Micro Detection】Intelligent Micro Motion Detection of Mid Deep Karst
Time：2023-8-7
Detection Location: Chongqing
Detection Equipment: Hefei Guowei Micromotion Detector GN209
Detection Purpose: To verify the development of deep karst in micro motion exploration by comparing the results of micro motion operations with the actual drilling situation.
Detection Parameters: Triple circle construction, with array radii of 50m-100m-200m, exploration depth of 1000m, acquisition time of 1 hour, and a total of 5 measurement points collected.
Detection Results:From the above figure, it can be seen that there are four signifucant low-speed anomalies near the survey lines at depths of 330m-420m,520m-540m,650m-710m and 810m-880m. It is speculated that they may be caused by the development of fractures and karst.
