My mine flooded the well in September 1978. After repeated invalidation, it turned out to be successful with grouting and water blocking. In September 1978, a well head south of the mountain was found 150 meters above sea level. The measured water inflow 1200 tons out of hours water point in the coal seam roof limestone (C_3L_1-2), the outlet width of about 10 cm long and 60 cm. The highest static water level of 182 meters, water temperature 19 ℃, the water point and the Carboniferous 9 limestone and the Ordovician limestone between the hydraulic connection has strong drainage seven times after a total of 105 days to discharge the total water 300 More than 10,000 tons, consumption of 2.18 million yuan of funds, the use of water
