Abstract: For problems existed in coal mine underground that persons cannot know environmental status entirely, safety inspector has no technical support equipment, managers cannot know safety status of underground production, and there is no mobile equipment of commanding information in emergency rescue, the paper proposed a whole design scheme of intelligent miner equipment system, and introduced functions and design requirements of main equipments in the system including multi environmental parameters collector, intelligent handheld terminal, intelligent master and wireless base station. It pointed out that key technologies and design difficulties are multi parameters sensing in underground environment, vital sign sensing of underground persons, wireless ad hoc network under disaster condition, information fusion of multi systems and power dissipation, volume and weight of equipments, and proposed corresponding solutions. Finally, it expounded application modes of the system in daily management, safety inspection and command of emergency rescue in coal mine.
