The invention relates to a mining flame-proof and intrinsic safety type direct-current stabilized power supply which comprises a flame-proof shell, a wiring terminal, a switching power supply, a circuit mainboard, a battery pack, a flame-proof control switch, a charging panel and a flame-proof through-wall terminal, and the flame-proof shell is composed of a shell body, a main cavity cover plate, a battery cavity cover plate and inner hexagon screws. The shell body, the main cavity cover plate and the battery cavity cover plate are fixed to form an explosion-proof face, a cable inlet, eight cable outlets, a grounding bolt and a switch knob are arranged on the right side of the explosion-proof shell, a main cavity and a battery cavity are formed in the explosion-proof shell, and the wiring terminal, the switching power supply, the circuit mainboard and the charging panel are installed in the main cavity. The battery and the explosion-proof control switch are installed in the battery cavity, the charging panel is connected with the battery pack in the battery cavity and the explosion-proof control switch through the explosion-proof through-wall terminal, when underground wiring or faults occur, electric connection between the main cavity and the battery cavity is disconnected through the explosion-proof control switch, and normal work of a system and workers in a mine is guaranteed.
