Accurate positioning method for favorable uranium ore sand body in coverage area

The invention belongs to the technical field of uranium mineralization favorable sand body prediction, and particularly relates to an accurate positioning method for favorable uranium mineralization sand bodies in a coverage area, which comprises the following steps of: 1, collecting and analyzing data, and delineating key prospecting basin sections and regions with larger potential; 2, determining a favorable prospecting target horizon; 3, supplementing and collecting drilling hole data for drilling through the favorable prospecting target horizon determined in the step 2, and counting data of various ore control elements of the target horizon; 4, drawing each ore control element map of the target horizon by utilizing Surfer software, and screening the most favorable mining area of each element; and 5, nesting and superposing various patterns, and accurately positioning the favorable uranium ore sand body. According to the method, all the favorable metallogenic elements are extracted and the most favorable m
