S2: starting a water pumping test, starting a deep well pump (4) to pump water, synchronously observing and recording the water pumping quantity of the deep well pump (4) of the water pumping drill hole, the water level of the water pumping drill hole (1) and the water level of the observation drill hole (3), and storing data in real time; measuring the water pumping time at 1, 2, 3, 4, 5, 10, 15, 20, 30, 40, 50 and 60 minutes after the water pumping is started, and observing the water pumping time at intervals of 30 minutes after a stable trend appears;
if the water pumping amount of the deep well pump (4) is suddenly reduced in the water pumping process, opening an electric control valve B (71), introducing water in a water storage tank (6) into the water pumping drill hole (1) through a water injection pipe (61), and performing flow compensation on the water pumping drill hole (1);
s3: recording and drawing a Q-s curve and s-t and Q-t curves on site, wherein Q is flow, s is depth reduction, and t is time;
s4: finishing the water pumping test;
s5: and according to the data of the water pumping test, selecting a proper formula to calculate the permeability coefficient K of the stable flow porous water pumping test and the influence radius R of the stable flow porous water pumping test.
