The Bureau of Mines of the Ministry of Economic Affairs instituted clear procedures about information delivery of mine safety during natural disasters. To improve the efficiency of mine safety procedures, this study has developed Mine's Light, a chatbot of natural disaster alert service. Mine's Light is designed based on human-computer interaction, featuring notification and retrieval of natural disaster decision-support information. The notification feature sends customized announcements to related personnel following the requirement of disaster management. The retrieval feature provides information about weather, disaster preparedness and response, regulations, and documents for users to query information by clicking menus or texting keywords. This study found that Mine's Light improves the efficiency of natural disaster information delivery procedures by featuring real-time notification and retrieval for users to obtain the required information.
