This invention belongs to the field of geophysical exploration technology and discloses a method for identifying the boundary of transient electromagnetic anomalies in mines based on DBSCAN clustering: Step 1, establish a three-dimensional geophysical model; Step 2, calculate apparent resistivity data using the small loop transient electromagnetic method; Step 3, draw a k-distance map and obtain the optimal neighborhood radius based on the k-distance map; Step 4, perform DBSCAN clustering on the apparent resistivity data to obtain the clustering results; Step 5, replace the apparent resistivity values ​​within each cluster with the cluster center values ​​to obtain the replaced apparent resistivity data; Step 6, image the replaced apparent resistivity data and identify anomalies; Step 7, compare the boundary of the anomaly with the boundary of the anomaly in the model. If the difference is too large, adjust the optimal neighborhood radius and return to Step 4; otherwise, use the current anomaly as the final identified anomaly. This invention can effectively identify the boundary of irregular anomalies in non-uniform and complex strata and can adapt to the real-time identification needs of underground anomalies.
