A New Way of Making Use of Heat Rock Mass Energy of Mine Underground

There is a new method for mine underground energy after summing up the traditional theory of geothermal energy usage, which is fracturing hot rock of mine and utilize the ground-cold water to wash out the hot rocks of mine, and then dip up and reuse those cold water when they turn to be warm. To establish permeability coefficient and seepage quantity model of three-dimensional fracture with the action of three-dimensional stress, the result shows how those stress affect the permeability.
