Abstract: For current status of lag in on-line health monitoring technology of coal miner and unrealized on-line monitoring of physical status of coal miners, the paper introduced whole structure of a kind of personnel location and health monitoring system of coal miner. It focused on technology of health monitoring sensor of coal miner, and proposed design schemes of body temperature sensor, pulse sensor, attitude sensor of rescuer and integrated vital sign monitoring sensor. The study result is important for preventing potential medical emergency events in coal mine.
