The present invention belongs to the recovering of dunderground saline mineral bed, and features the hydraulic pressure burst communicating in well group inside the saline mineral bed; and regulating the water injecting walls and discharging wells based on the pressure different distance between injecting wall and discharging wall during the production. The said process can control the homogeneous dissolution of rock saline mineral and homogeneous deposition and reach the recovering of salt mineral in low cost, high recovery ratio, high efficiency and no environment pollution. |
