Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, and in particular to a gamma spectrum measuring device. Background Art

[0002] At present, in the fields of geological exploration, nuclear environmental monitoring and mineral resource investigation, gamma spectroscopy measurement technology has become an important means to obtain the content of radioactive elements such as uranium, thorium and potassium. Existing gamma spectroscopy measurement devices usually adopt a single-point measurement mode composed of a single detector and a collector. Its working principle is to obtain gamma ray spectrum data at a specific location through the detector, and invert the content value of the target element after signal processing. This technology can achieve effective measurement in areas with good geological homogeneity, but it has significant limitations in complex geological environments.

[0003] The main problems of existing gamma ray spectrometers include:

[0004] (1) Single-point data is not representative enough: Single-point measurement only reflects the radioactive characteristics of a local area. When there is an uneven distribution of uranium, thorium and potassium elements in the measured area (such as alternating distribution of mineralized zones and surrounding rocks), single-point data cannot accurately represent the regional background value, resulting in deviations in subsequent anomaly identification and mineralization trend analysis.

[0005] (2) Poor dynamic adaptability: The acquisition range of traditional devices is fixed, and it is difficult to flexibly adjust the measurement area according to changes in geological conditions. For example, in contact zone deposits, the radioactivity difference between the ore body and the surrounding rock is significant, and a fixed acquisition range can easily lead to dilution of high-grade mineralization information or neglect of low-grade anomalies.

[0006] (3) Low measurement efficiency: Single-point measurement requires obtaining data point by point through manual mobile equipment, which is time-consuming and labor-intensive in large-scale exploration scenarios. In addition, the continuity between adjacent measurement points is difficult to ensure, which affects the accuracy of data spatial interpolation.

[0007] To address the above problems, existing technologies attempt to achieve multi-point measurement by increasing the number of detectors or using vehicle-mounted scanning systems, but they have defects such as unadjustable acquisition range, bulky equipment, and high cost. For example, multi-detector arrays are usually arranged at fixed intervals and cannot adapt to geological anomalies of different scales; although vehicle-mounted systems can achieve continuous measurement, they are limited by mechanical structures and are difficult to be flexibly deployed in complex terrain. Summary of the invention
