The utility model relates to circuit arrangement of a mining intrinsic-safe speed sensor, which is characterized by mainly comprising three parts, i.e., a frequency output circuit (1), a speed control circuit (2) and a nixie tube display circuit. The frequency output circuit (1) is installed in a roller of the mining intrinsic-safe speed sensor; a frequency amount output terminal of the frequency output circuit (1) is connected with a signal reception terminal of the speed control circuit (2); and a nixie tube (3) is connected with a display output terminal of the speed control circuit (2). The circuit arrangement of the mining intrinsic-safe speed sensor is convenient to use and also convenient for underground maintenance, wherein it is only required to fix a support on a stand of a belt conveyor via a built-in steel cable to enable the roller fall freely onto a belt; and equipment sealing performance of the circuit arrangement is good, mechanism of same is simple, and the circuit arrangement basically belon
