The environmental benefits of UCG are mainly due to eliminating (i) conventional mining operations, (ii) the presence of coal miners in the underground, (iii) coal washing and fines disposal, and (iv) coal stockpiling and coal transportation activities. Furthermore, UCG has a capacity of great potential to provide a clean coal energy source by the implementing carbon capture and storage techniques as part of the energy extraction process. In this method, coal seams in the underground were converted into syngas including hydrogen (H ), carbon monoxide (CO), carbon dioxide (CO ), and methane (CH ) gasses with an advanced 2 4 thermochemical process. UCG operation effected significant geomechanical changes to the overburden strata. In this process, the vertical well (especially
