Digital Mine and Intelligent Monitoring and Warning of Coal Mine Gas Protrusion and Explosion

Combined with the development and application of Coal Mine Gas Protrusion and Explosion System （CMGPE）, this paper introduced the main ideas, key technologies, system functions, and application effects in the intelligent monitoring, analysis, display and early warning of coal mine gas protrusion and explosion based on Digital Mine technologies. The protrusion amount of mine gas and the occurrence of dynamic phenomenon of gas outburst are influenced by the factors of geology, crustal stress, and mining conditions, etc. The datasets involved in an effective prediction of CMGPE are often characterized by their muhiple sources, spatial and temporal references, and their dynamic spatial-temporal variations. GIS technology, virtual reality technology and other spatial information technologies have a great potential of applications in the monitoring of coal mine gas concentration and early warning of CMGPE. Effective applications of the Digital Mine technologies will further transform the practices involved in the monitoring, analysis, visualization and early warning of CMGPE, with greater social, economic and environmental benefits. The construction of Digital Mine has great promoting functions for safety production of coal mine.
