In order to effectively solve the contradiction between the increasingly prominent coal resource exploitation and the fragile ecological environment,based on regional geological data of Yushen Mining Area,the poper selected more than 500 drills distributed on the whole mining area uniformly,counted every drill's first coal seam and combination of aquifer and aquifuge,meanwhile,it considered Luohe group that were considered seldomly on the existing results,and seen Luohe Group water as protected object,combined with occurrence characteristics of first coal seam,aquifers as well as aquifuge,and then,it adopted the principles of"similar within district and different out district"and"serve for protecting water resources during coal mining action"to zone the engineering geological conditions of protected water resources during coal mining action,finally,the Yushen Mining Area's engineering geological condition are divided into five types,sand-clay-luo-bedrock water mining area,sand-clay-bedrock" water mining area,sand-bedrock water mining area,no water mining area and burnt rock area.On this basis,the authours discussed every type's possibility and difficulties for protected water resources during coal mining action.This paper aimed at promoting the development of protected water resources during coal mining action,realized the scientific exploitation of"coal-water"dual-resource mining in Yushen Mining Area.
