Study and Application of Temperature Distribution Field Model of Collapse Column Surrounding Rock under Action of Groundwater Seepage

The water inrush from the collapse column may lead to the temperature rise of its surrounding rock,so it has a certain feasibility to predict the mine water inrush according to the temperature field distribution of the surrounding rock.With the finite element software COMSOL solving temperature-seepage coupling model,the temperature field distribution of the surrounding rock of the collapse columm in 7₂22 working face after water inrush was got,the simulating and monitoring results were basically identical,this indicated that it was feasible to predict the possibility of mine water inrush by monitoring the temperature field distribution of the water-bearing structures.The simulating results showed that the closer the distance to the high-temperature water flow,the longer the affacting time by the heat balance area,and the more significant the change of the temperature field.
