"Ventilation, fire prevention, gas control, and dust prevention" (Yitong Sanfang) in underground coal mines is a core link to ensure safe production. Traditional early warning systems have problems such as data lag and insufficient simulation accuracy. Digital twin technology provides a new solution for dynamic early warning by establishing real-time mapping between physical mines and virtual mines. The system integrates multi-source monitoring data such as ventilation, gas, fire, and dust to realize real-time simulation and trend prediction of underground environmental parameters. With the help of virtual simulation, it can simulate the diffusion path and influence range under abnormal working conditions, trigger early warning in advance and generate disposal plans. This not only improves the response speed of early warning but also enhances the accuracy of risk prediction, providing intelligent technical support for the safety management of "Yitong Sanfang" in underground coal mines.
