Abstract: At present,the computer are extensively used in production of coal mine,the flameproof or flameproof and I.S.computer do not suit the development of mining industry.The paper discussed the design principles of compatibility,expandability,dustproof,shockproof,dampproof and low power consumption of mine-used I.S.computer,and analyzed the technical problems of realizing the mine-used I.S.computer,including the problems of power consumption such as display device,HD and CPU.At last,it provided the implementing method of mine-used I.S.computer.
