Abstract The theory of thermal diffusion in surrounding rocks affected by mining around the water-bearing structure is studied. The new style advanced model test device and similar material of typical hydro-mechanical coupling is used and the monitoring system of grating temperature and displacement is improved. The coal mining around the water-bearing structure is simulated by tests. The variation laws of seepage and temperature fields induced by deformation of overburden rock during mining are analyzed. There is obvious abnormal temperature feature in the intact rock mass around the water-hearing structure before mining. The temperature of rock mass reduces gradually with the mining. Temperature response feature of water inrush is obvious in layered rock mass upper the gob. The temperature fitting curve of rock mass is concluded with the data of the model test. It provides the theoretical foundation for the forecasting water with rock mass temperature method.
