Zholudyev S. Basing technical parameters of underground brown coal gasification and incineration with ground water application

The thesis is devoted to improve technological parameters of heat energy modules based on Underground Coal Gasification (UCG) and Underground Coal Incineration (UCI) technology.Underground Coal Gasification and Underground Coal Incineration are combining excavation with simultaneous underground processing in entire technological process. It's difficult and requires additional specific measures for optimization of underground combustion, concentration and transportation of products, and stabilization of worked out and flooded space. For solve these problems possible use intermediate moving heat carrier. Flow controlled ground water within thermal zone can be used as heat carrier.The Numeric Modeling and Analyzing of gas-, hydro- and thermodynamic processes under UCG and UCI technologies were needed for the better understanding of the process. For it's solution the various numerical methods are used. The possibility to use ground water as heat carrier was also estimated. The results of calculation show the character of an underground generator thermal and pressure fields. As a result were developed technical parameters of energy modules UCG and UCI. An application of such energy modules allows increasing advantages and efficiency of coal extraction.
