Method for correcting soil-gas radon instantaneous measurement data in uranium ore exploration and prospection

Abstract

The invention belongs to the technical field of exploration and prospection of uranium resources, and in particular, relates to a method for correcting soil-gas radon instantaneous measurement data inuranium ore exploration and prospection. The method particularly includes the steps: step one, synchronously measuring soil-gas radon in multiple measurement points of a work area; step two, calculating a measurement data correlation coefficient; step three, determining horizontal and vertical intervals of a division measurement unit; step four, dividing the measurement unit; step five, determining measurement unit observation points and recording the gas radon concentration values of the observation points; step six, carrying out area measurement of the measurement unit; step seven, dividingthe time period, and calculating the correction coefficient; and step eight, determining the measurement unit correction value, and correcting data. The method can effectively reduce errors, caused due to different measuring time, between different measurement points of the same work area, makes the measuring time of different measurement points of the same work area unify to a same time, and more truly reflects soil-gas radon field distribution characteristics in the work area at the same time point; and a data splicing problem of different work areas in different years also can be solved.

Description

technical field [0001] The invention belongs to the technical field of uranium resource exploration, and in particular relates to a correction method for instantaneous soil radon gas measurement data in uranium ore exploration. Background technique [0002] Radioactive prospecting methods are widely used in the prospecting of uranium resources. Soil radon measurement is one of the routine radioactive prospecting methods. The principle of the method is to measure the radon concentration in the soil and evaluate its mineralization potential according to the level and distribution characteristics of the radon concentration in the soil in different regions. The measurement of soil radon gas can be divided into cumulative measurement and instantaneous measurement. The instantaneous measurement of soil radon gas has the characteristics of low economic cost, high work efficiency, and on-site data acquisition, and plays an important role in the exploration of uranium mines.
