Abstract: For problems of high labor intensity and low data collection efficiency existed in integrated water inrush monitoring system of coal mine, distributed sensor node, routing node and sink node of hydrological parameters and rock stress are developed on the basis of ZigBee wireless sensor network architecture. A distributed water inrush monitoring system of coal mine was established. Hydrology monitoring and rock stress monitoring are integrated in an unified network. Online dynamic change of mine hydrological parameters and rock stress can be gotten real-timely through upper computer processing collected data. Testing result shows that the system has high detecting precision.
