The emergency rescue for coal mine disaster is very important to mine security. The environments of coal mine is complicated and dangerous. In order to ensure the self-security of rescuer, minimizing the accident losses, the emergency rescue life sign monitoring sensor based on Fiber Bragg Grating(FBG) and three-axis acceleration sensor are studied in this paper. Firstly, the structure of the emergency rescue system for coal mine disaster is built. Then the life sign monitoring sensor of emergency rescue system for coal mine disaster is studied in detail, includes the detection model of body temperature, the heart rate detection technology for rescue staff, and the detection method of rescue staff posture. Finally, the experiment is made to test the effect of the sensor. The results show that the sensor sensitivity to rescue staff life sign is higher, and it can satisfies the needs of the emergency rescue for coal mine disaster
