Research on the distributed “river-subsidence area-groundwater” coupling simulation of coal mining subsidence area: Ⅱ: application

  • Ascertaining water supply and drainage routes and water resource conditions can provide technical support in the comprehensive treatment of coal mining subsidence areas. The subsidence conditions in the Huainan Panxie coal mining area in 2010 and the meteorological data from 2001 to 2010 were used to simulate the local water cycle in mining subsidence areas in recent years by the distributed "river-subsidence depression-groundwater" coupling model, and the model has been verified. The results show that river confluence, precipitation, groundwater, and runoff formed 84.6%, 8.8%, 3.6%, and 3.0%, respectively, of the water supply. River discharge, evaporation, seepage, and water diversion constituted 80.6%, 8.2%, 1.3%, and 9.9%, respectively, of the water drainage. River confluence is the primary factor influencing the water cycle, followed by precipitation and evaporation, with groundwater exerting a negligible influence.
