The invention provides a method for inquiring the detonator in the priming circuit of an electronic detonator. The method comprises a detonator inquiring process of a priming device on one hand and an inquiring process of the electronic detonator on the other hand. Firstly, the priming device carries out roll-calling process: that is, sending a roll-calling instruction to a detonator which is not roll-called; waiting for receiving roll-calling response information sent back by the detonator; and placing a roll-calling completion marker if the roll-calling response information is received, or adding the information to an un-responded detonator information list if the roll-calling response information is not received. Next, the priming device carries out novelty searching process after the external confirmation information is received, and the process comprises the following steps: sending instructions for examining a new detonator to all the electronic detonators; and displaying the new detonator existing information after the information is received and finishing, or finishing directly if the information is not received. The technical scheme provides a method which can inquiry all the detonators in the priming circuit of the electronic detonator, thereby improving the fault treatment efficiency of the priming circuit of the electronic detonator to ensure that the priming circuit is more reliable.
