According to the difficulty problem to get the vibration acceleration singles in present underground mine, the research and development method of the mi ne intrinsic safe mode vibration sensor was studied. The vibration acceleration sensor with the built-in integrated circuit amplifier IC was applied.With the mine fire resist ance electric cable connected with the signal control module, a 21 V intrinsic safe electric power was applied to supply the power to the signal control module.The intrin sic safe power supply control module for the design of the signal control board was applied to supply the power for the vibration acceleration sensor and could have the control function of the vibration single.The intrinsic safe parameters measured by the instrument were the intrinsic voltage of DC21 V, the intrinsic current of 65 mA, the intrinsic capacitance and the intrinsic inductance is zero individually.The collection and measurement were conducted on the standard vibration signals (frequency 159. 2 Hz) .The results showed that the research and development program of the mine intrinsic safe mode vibration sensor was feasible.
