Hydrogeological condition of Xihe Coal Industry was introduced in this paper, water level elevation of Ordovician karst fractured aquifer in field was pointed as 805～803 m and No.10 coal seam in field was mining coal seam with pressure. No.10 coal seam of Ordovician hydrogeological conditions under pressure needed to be evaluated to provide a reference to further compensated mining in No.10 coal seam.
