Combined prospection method for predicting uranium ore body burial depth

Abstract

The invention belongs to a uranium ore exploration method, and particularly relates to a combined prospection method for predicting the uranium ore body burial depth. Specifically, the method includes the following steps of determining measuring positions in a measuring area, measuring the content of ground gamma energy spectrum uranium at the measuring positions, measuring the content of instantaneous soil radon gas at each measuring position, taking soil samples at the measuring positions, airing, pulverizing and screening the soil samples, drying the soil samples, using agentia to extract component uranium in the dried soil samples, measuring and determining the extracted adsorbed state component uranium, making a plane contour map, circling an abnormal area, and predicting the uranium ore body burial depth according to abnormal combination conditions of the energy spectrum uranium, the instantaneous soil radon gas, the component uranium, the instantaneous soil radon gas / energy spectrum uranium ratio, the component uranium / energy spectrum uranium ratio and the component uranium / instantaneous soil radon gas ratio. According to the method, the misering workload can be greatly reduced, the prospecting hit rate is improved, and cost is reduced.

Description

technical field [0001] The invention belongs to a uranium ore prospecting method, in particular to a combined detection method for predicting buried depth information of uranium ore bodies through ground gamma energy spectrum measurement, soil instantaneous radon gas measurement and component uranium measurement. Background technique [0002] Uranium resources are dual-use resources for both military and civilian purposes. With the rapid development of the national economy, especially with the development of nuclear power, the demand for uranium ore is increasing, and uranium ore resources have become an important pillar for the sustainable development of nuclear power in my country. With the deepening of ore prospecting, most of the superficial ore and outcrop mines have been discovered. In recent years, geological prospecting has gradually developed in depth to search for deep hidden uranium ore bodies. As the depth of prospecting continues to increase, the original conve...

AI Technical Summary

Problems solved by technology

As the depth of prospecting continues to increase, the original conventional exploration technology can no longer meet the needs of scientific research and production, so a series of deep-penetrating geochemical detection technologies for the exploration of deep concealed uranium deposits have emerged, such as geochemical Gas method, enzyme extraction method, geoelectrochemical method, metal activity dynamic measurement method, etc.

These methods can detect deep uranium ore bodies, but cannot give information about the buried depth of the ore body, which brings difficulties for later uranium exploration. A detection method that can give the buried depth of the ore body is urgently needed
