Abstract: In order to obtain engineering design basis information of optimizing Ordovician limestone drainage water, a fine three-dimensional seismic exploration was made in mining area of West one. Through the three-dimensional seismic exploration, the structural shape of Ordovician limestone top interface and the fault whose gap is greater than 3 m are identified, and exploration geophysical anomalies within the area is delineated, and the distribution ranges of 10^#, 13^# coal seam and its structural forms are identified. The 10102 and 10104 working face drainage water schemes are optimized and designed by exploration results, and the 10102 and 10104 faces are mined safely with grouting transform mining cost savings of 10.699 million yuan and 206 000 tons of coal recycled, and industrial output value of 74.16 million yuan is added.
