In view of the water outburst damage in the closed small coal mine mining area, the water outburst channel was found by means of geophysical detection, microseism, drilling and Ordovician limestone water level network analysis. The water outburst channel and water outburst source were completely blocked by the combination of curtain and grouting aggregate and multi-layer cross reinforcement technology, compared with the same period in the past, the overall water inflow of the mine is reduced by 62 %,greatly reduced the cost of mine drainage,protected the water resources of Ordovician limestonewhich provided a guarantee for the safe production of the mine.
