According to the actual environment and condition of coal mine, we proposed a data aggregation model for wireless sensor networks to enhance the real-time performance and the reliability of underground environment monitoring system. In this model, all sensor nodes were divided into different grid clusters by geographical information and the network topology was composed of two levels. The lower level including all ordinary nodes was responsible for environment monitoring and delivered the data to the upper level, all the cluster head nodes formed the upper level which took charge of local data collection and establishment of the routing paths to sink. This paper discussed the details of this data aggregation model and the simulation results showed that this data aggregation model was efficient in cutting redundancy data and reducing transmission delay. It was suitable to be applied to the real time monitoring networks in coal mine.
