Underground Coal Gasification Pollutant Extraction Numerical Value Simulation

In our test site for an underground gasification research background, using Visual Modflow in Modflow, MT3DMS and MDPATH of modules to flow model and solute transport model as the basis for underground gasification process occurring contaminants leaked as the premise, to establish the extraction of the base model of groundwater pollution, contamination of drinking water layer obtained after the extraction treatment leak effect: the aqueous layer extracted with increase in the amount of pollutants is gradually decreased, when the pump is greater than or equal to 5000m3, contaminated aquifer things fell background. Actual extraction site monitoring results with the predicted results are the same, in order to verify the reliability of the numerical simulation, and ultimately for the underground coal gasification process made possible contaminant spill contingency processing methods, environmental protection technology that provides a reference.
