The invention belongs to the technical field of electromagnetic starters and specifically relates to a mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter. The invention solves technical problems and provides the dual-circuit vacuum electromagnetic starter capable of measuring liquid level of a shaft sump and pipeline flow of a mine and automatically controlling two water pumps for water discharge. The technical scheme is that the mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter includes a shell body inside provided with two independent explosive-proof cavities; the two independent explosive-proof cavities are respectively inside provided with a host and a standby machine; and each of the host and the standby machine includes a comprehensive protector BH1 and a vacuum contactor KM1. The mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter provided by the invention is suitable for the field of electromagnetic star
