In order to strengthen the monitoring of floor water damage under the condition of mining with pressure in the thick coal seam of Tangjiahui Mine and give full play to the advantages of micro-seismic real-time monitoring in a large range, a micro-seismic monitoring system for deep coal mine of Tangjiahui Mine was constructed. The percussion experiment showed that the positioning error of micro-seismic monitoring system was less than 6 m.The water inrush early warning model of 61303 working face was constructed to analyze the spatial distribution, time and energy characteristics of micro-seismic events during mining, and to study the relationship between mining activities and micro-seismic monitoring. The results showed that the micro-seismic activities in the mining face during the monitoring period were mainly divided into active and static period, and the micro-seismic events were concentrated in the mining operation period, which were obviously affected by mining, most of them were weak energy events in the shallow part of the coal seam floor, without water inrush risk.
