Abstract In recent years, the speed and depth of coal mining were increasing, and the water disaster of limestone water in deep floor became more and more prominent. The construction of coal mine water disaster monitoring, forewarning, prevention and control system played an important role in the prevention and control of coal mine water disaster. This paper took Pingdingshan No.10 Mine as an example to explain the system function. The water abundance abnormal area in the working face of No.10 Mine of Zhenping Coal Mine was dense and threatened by Cambrian limestone water. Therefore, the microseismic monitoring system was set up in multiple working faces to construct an automatic monitoring and forewarning platform for water disasters. The system adopted modular design, fully combined the actual geological conditions and hydrological information of Pingdingshan No.10 Mine, through the fusion analysis of multi-source data such as mine pressure, geophysical exploration and microseism, embedded model algorithm, quantified forewarning indicators, integrated GIS function, and realized the dynamic evaluation and trend prediction of floor water disaster. The practical application showed that the platform had stable operation, timely response and high forewarning accuracy, which was of great significance to improve the ability of mine water disaster prevention and control.
