A hydrogeological conceptual model was set up based on the analysis of geological structure. The 3# group coal bed within Shanxi Formation was conceptualized as a confined aquifer, overlaid by Permian sandstone and mudstone and underlaid by interbeds of mudstone and sandstone functioning as quitards. In addition, groundwater boundary conditions were confirmed. Migration of hydro-fracturing fluid in coal bed of the study area was modeled and predicted. Results indicate that the migration range of hydro-fracturing fluid in the coal bed is within coal hydro-fracturing impact limits, about 300 meters around fractured well
