Abstract: A method and system for exploring hidden karst pipelines, mainly comprising: determining an upstream and a downstream of an underground karst pipeline; laying a grounding electrode at the upstream and the downstream respectively; establishing an electromagnetic emission system through underground karst water channels in the underground karst pipeline in a survey area, a transmitter and a generator; arranging a receiving system through an air mobile equipment towing a receiver as a receiving end; turning on the electromagnetic emission system; a generator supplying power to emission circuit; controlling the air mobile equipment to move along routes to collect signal continuously above the survey area, to complete an area-based measurement, and obtain observed data in the whole survey area; processing the observed data; delineating a concrete distribution of the underground karst water channels from the to the, such as a net-shaped path diagram or a tree-shaped path diagram
