    A model describing cavity growth and gas production during underground coal gasification (UCG) has been developed. It is applicable to UCG of shrinking coals in which oxidant injection is maintained at a fixed point low in the coal seam. It is based on a few fundamental assumptions; namely that the cavity is axisymmetric about the injection point, all resistance to injected gas flow is through ...

    Reactor Model for the Underground Coal .

    Underground Coal Gasification (UCG) is the process of in-situ conversion of coal into combustible products (syngas) which can be used either as fuel or as a chemical feedstock. In this study, the gasification channel is viewed as a one-dimensional packed bed reactor. The packed bed reactor model is solved incorporating chemical reactions and mass transfer effects. A pseudo-transient model is ...

    Modeling Cavity Growth during Underground Coal Gasification · Fichier PDF

    Abstract: Underground coal gasification (UCG) has received renewed interest due to its potential for utilization of the vast amounts of coals available in deep underground seams and the current drive towards clean coal utilization. The UCG process involves the reaction between steam and coal in deep underground seams to form a combustible gas which is brought to surface via a production well ...

    Different from the traditional methods in the study of underground coal mines, we tried to use model to analyze and predict the incidence trend of CWP. The model could reduce the limitations in the calculation of age-specific incidence rate and age-adjusted incidence rate which were usually used in traditional methods 26, 27]. It can describe the incidence trend of CWP in different ...
