Abstract: With the large-scale mining of coal resources, there are more and more potential hazards of coal mine geological disasters. Coal mine disaster accidents often have the characteristics of suddenness, contingency and complex. Information technology can quickly integrate and process multi-source information, which is an important support for effective rescue. The article is based on the actual situation of coal mine safety production, combined with the business characteristics of geological exploration units, based on the analysis of system requirements, this paper designs the system functions, puts forward the key technologies and implementation methods of system construction, and develops and constructs an information system that meets the actual needs of coal mine geological emergency rescue. Taking a coal mine in Ningnan Coalfield as an example, the rationality of the system function is verified.
