Airborne gamma spectrometry information processing method for indicating deep uranium anomalous block

Abstract

The invention belongs to the field of radioactive geophysical exploration in uranium exploration, and particularly relates to an airborne gamma spectrometry information processing method for indicating a deep uranium anomalous block. The method comprises steps: 1, a target basin is selected to be explored; 2, calibration result parameter data are inputted to the system; 3, a measuring line distance is designed to measure the target basin; 4, U and Th content scatter data in the third step are subjected to Kriging interpolation; 5, raster data in the fourth step are subjected to sliding treatment; 6, according to the MU and MT data acquired in the fifth step, MT / MU is calculated, the CT in the second step is divided by the MT / MU, and the result is marked as RU; 7, the CU in the second stepis subtracted from the RU in the sixth step, and the calculation result is marked as AU; 8, the SU in the fifth step is divided by the MU, and the result is marked as U<CV>; and 9, the AU in the seventh step and the U<CV> in the eighth step are multiplied, and the result is marked as DI. A deep uranium anomalous block can be indicated effectively, and deep sandstone-type uranium deposit prospecting is guided.

Description

technical field [0001] The invention belongs to the field of radioactive geophysical exploration in uranium ore exploration, and in particular relates to an airborne gamma energy spectrum information processing method for indicating deep uranium abnormal blocks. Background technique [0002] With the discovery of the Daying uranium deposit, a deep sandstone-type uranium ore prospecting boom was set off. However, the strong radioactive anomaly of the sandstone uranium ore body and the strong wall rock alteration information have experienced layer-by-layer barriers of wall rock and caprock during the transmission process. , when it reaches the surface, the anomalous information is very weak, or even not reflected. Aeronautical gamma energy spectroscopy is to install a special aviation gamma energy spectroscopy instrument on the plane, and fly continuous point measurement in the air at a distance of about 200m from the meter. The body effect within the range of flying distance...
