Abstract: For the limitations of traditional fire-control techniques like stripping, water injection and grouting that a lot of heat is abandoned without utilization in the process of coal fire control, a new thought in controlling coal fire, which can be called "replacing coal fire control with heat utilization", is proposed in this article that the heat energy in coal fire areas should be exploited and utilized as a kind of clean energy to realize the control of coal fire. Heat transfer medium and heat extraction method, thermoelectric conversion method and their corresponding applicability are analyzed. Besides, the multi-hole press-style and oriented heat extraction method as well as heat conversion method are proposed, these methods use low-temperature gaseous medium as main heat transfer medium and adopt Organic Rankine Cycle system to complete thermoelectric conversion, based on which, the possible problems needed to be further resolved before implementation are analyzed.
