Abstract:: The phenomenon of the double -layer leak drainage sewing pores found from the decompression and normal pressure test, which is verified by the dual water cave test, which proves that it is a gas zone and explains the cause of this gas band. The result has a practical guidance effect on the causes of the destruction of the Sanmenxia double -layer holes and sloping door slot guide rails to the correct judgment of the Sanmenxia double -layer hole slot guide rail.
