Because of partial pressure of Ordovician limestone water in No.4, 9, 11 coal seams in Ermugou Mine, water inrush of Ordovician limestone water might occur. Based on this problem, feasibility evaluation of Ordovician limestone water to mining under pressure in No.4, 9, 11 coal seams was analyzed through evaluation of its security and analysis of elements and conditions of mining water inrush.
