    • Abstract
  • In Northern China type coal field,Ordovician Karst fissured aquifer has hydrodynamic relation to the aquifer in coal-bearing series by the vertical conductor(VC).Because of VC's hiding and limited cross-section area,it is hard to find its location by conventional hydrogeological prospecting methods.In Kailuan and Feicheng Coal Bureau etc.,we have chose a certain aquifer between lowest coal seam and Ordovician aquifer as "medium indicative aquifer",to find "hydrogeological abnormal region"(HAR).Through dewatering test,we have further reduced the scope of HAR,discovered three vertical conductors.By test examples,it is illustrated that above-mentioned method is feasible to find vertical conductor in abundant water coal mine similar to hydrogeological conditions.
