The invention discloses an intrinsically safe network voice controller for mining, comprising a CPU (central processing unit) circuit, wherein the CPU circuit is respectively connected with a network processing circuit, an SD (Secure Digital Memory) card circuit, two paths of audio coding and decoding circuits, an audio drive circuit and a power supply circuit for supplying power, the two paths of audio coding and decoding circuits are connected with at least one path of audio interfaces through the audio drive circuit, and the SD card circuit is directly connected with the audio coding and decoding circuits. The intrinsically safe network voice controller for mining, disclosed by the invention, is a part of underground digital broadcast of a coal mine, the digital broadcast is transmitted by a network, so that the signal to noise ratio is high, the transmission distance is far, and the digital broadcast has an advantage incomparable to that of the traditional constant pressure broadcast method. The intrinsically safe network voice controller for mining is suitable for such occasions as an underground sidewalk of mine, a parking place and a rest room, etc.
