- Abstract
According to the example of the pumping test with one hole in confined aquifer above the Baode coal seam gas mining area in Shanxi Province, Jacob linear graphic method applying the least-squares method based on relative error was proposed to calculate parameters, and compared with conventional methods such as Thies fitting curve method, conventional Jacob linear graphic method and water level recovery method. The results show that the hydraulic conductivity coefficient and the storage coefficient are 347 m2/d and 0.000 57 respectively, which proves that the improvement method is more reasonable and perfect than the Jacob linear graphic method.
