description The invention belongs to the technical field of mine water prevention and control, aims to solve the prominent problems of risk control and the like in the mine underground large-volume high-pressure-bearing water-containing body drainage scheme design and drainage construction process, and achieves the purpose of safe drainage. The invention provides a drainage construction method for a large-mass high-pressure-bearing water-containing body under a mine shaft, which comprises the following steps of: reserving a waterproof and waterproof rock pillar, implementing drainage drilling by using a double-layer water stop sleeve and an orifice safety device which are pre-buried in a stratum, and controlling drainage of the water-containing body through a pipe orifice control valve; the method specifically comprises the steps that the width of a water-proof and water-proof rock pillar is reserved; the diameter and number of drainage holes are determined according to the static reserves, the dynamic water volume, the
