通过室内和现场试验，验证了热管对地下煤火热能的去除能力。热管是一种导热系数很高的装置。通过使用热管，可以将大量的热量从地下输送到地面。热管中充满了根据当前温度范围选择的工作流体。热量从煤火施加并传导到热管的蒸发器部分，使液体蒸发。蒸汽移动到表面上方的冷凝器部分。蒸发流体被冷凝，冷凝液在重力作用下回流到蒸发器段。当流体在那里凝结时，从火中取出的能量迅速转移到冷凝器部分。从那里，能量最终会流向周围的空气，延伸的冷却区域（桨）可能会促进这种转移。安装后，该进程将持续运行。
The ability of so called heat pipes to remove thermal energy from the underground coal fire was tested by laboratory and field experiments. A heat pipe is a device of very high thermal conductance. By using a heat pipe, considerable quantities of heat can be transported from the underground to the surface. The heat pipe is filled with a working fluid selected for the present temperature range. Heat is applied and conducted from the coal fire to the evaporator part of the heat pipe and causes the liquid to vaporize. The vapor moves to the condenser section above the surface. The vaporized fluid is condensed and the condensate flows back to the evaporator section by gravity force. The energy removed from the fire is rapidly transferred to the condenser section when the fluid condenses there. From there the energy will finally flow to the surrounding air and extended cooling areas (paddles) may facilitate this transfer. Once installed, the process will run continuously.
