The invention relates to a mining flame-proof and intrinsically safe type anti-explosion computer. A bakelite plate is installed on one side panel inside a box, wherein a mainboard, a power source, afilter, a hard disk and a pinboard are fixed to the bakelite plate, the front side panel of the box is an intrinsic safety wallboard, an anti-explosion junction box is fixed to the upper portion of the intrinsic safety wallboard, an outer connector is fixed to the lower portion of the intrinsic safety wallboard, an amphenol connector is communicated with the box and an inner cavity of the anti-explosion junction box, an anti-explosion connector is fixed to the anti-explosion junction box, one end of the anti-explosion connector is in data connection with the amphenol terminal through a connecting line, and the other end of the anti-explosion connenctor is connected with peripheral equipment; a power line is connected with a power panel through the outer connector, the power panel is connected with the mainboard through the filter, a radiator is installed on the mainboard, the mainboard is connected with the intrinsic safety pinboard, the hard disk is plugged to the mainboard, and the intrinsic safety pinboard is connected with the amphenol connector. The anti-explosion computer is good in heat dissipation performance, reasonable in structural design and high in anti-explosion coefficient.
