摘　　要：随着开采深度的增加,煤层底板突水成为影响矿井安全生产的重要地质灾害之一。以水峪煤业2号煤层带压开采为工程背景,对奥灰水地下水流场、富水性及隔水层阻水能力等进行分析,并采用突水系数法对2号煤层突水危险性进行计算,得到底板奥灰水突水系数为0.0102~0.0403 MPa/m,突水系数值均小于0.06 MPa/m,确定突水危险性分区为Ⅰ区,属于带压开采相对安全区。为避免矿井水害的发生,制定了带压开采技术措施,保障了水峪煤业的安全生产。With the increase of mining depth,water inrush from the coal seam floor has become one of the important geological hazards affecting mine safety production.Taking the pressurized mining of 2#coal seam of Shuiyu Coal Industry Co.,Ltd.as the engineering background,this paper analyzed the underground flow field of Ordovician limestone water,water-rich and water-blocking capacity of the water-barrier layer,and calculated the water inrush risk of 2#coal seam by using the water inrush coefficient method,and obtained the water inrush coefficient of the Ordovician limestone water on the floor as 0.0102-0.0403 MPa/m.The water inrush coefficient values were all less than 0.06 MPa/m,and the risk zone of water inrush was determined to beⅠzone,which belonged to the relative safe zone of pressurized mining.To avoid the occurrence of mine water damage,pressurized mining technology measures were formulated to ensure the safety production of Shuiyu Coal Industry Co.,Ltd.
