Abstract:Due to over exploitation of underground brine water in many years, many underground brine funnels have been formed in south coast of Laizhou Bay. Based on long term observational datas of water level in brine mining field, dynamic changes of underground brine water level are analyzed systematically, the relationship between the brine water level and the mining amount is identified, and the correlation equation is established. As showed by the equation, the water level is directly determined by the mining amount. It will provide a scientific basis for improving geological environment and rational use of brine resources.
