摘　　要：根据水位场、水温场、水化学场一致性的理论,快速判别出任楼煤矿7218掘进工作面突水水源为深部奥灰水;导水通道为隐伏导水陷落柱(定性)。通过封堵出水巷道,防止水量由渐变到突变(预防);井下物探、钻探等综合探查确定隐伏导水陷落柱的位置、范围与空间形态(定位);采用计算机仿真技术,模拟了隐伏导水陷落柱内应力场、位移场和渗透场的动态特征,通过优化设计确定在其顶部注浆建立"穿裙盖帽的止水帽"充填加固技术方案(超前治理),避免重大恶性突水事故的重演,取得了"高效快省"的定性预防定位超前探查治理隐伏导水陷落柱的新模式。According to the theory of consistency of ter chemistry field, the deep ordovician limestone the water level field, water temperature field, wawater has been distinguished quickly as the water sources of water inrush served as the heading face of 7218 in Renlou coal mine. The water--conducting channel is the insidious water conducting collapse column （quality）. By plugging the produced water roadway, the water quantity has been prevented from the gradual change to catastrophe（prevention）. The location, extent, and spatial forms of the insidious water conducting collapse column have been determined by synthetical methods of geophysical and drilling exploration（localization）. The dynamic characteristics of the stress field, displacement field and penetration field in the insidious water conducting collapse column have ben simulated by means of computer simulation technology. A scheme of filling reinforcement to establish watertight cap which is like wearing skirt and covering cap by grouting on the top of the insidious water conducting collapse column has been determined by optimizing design（governing in advance）. To do these, the recurrence of significant and vicious water inrush accident has been avoided. A new high efficiency, quickness and saving pattern from quality, prevention, localization, exploration to governing the insidious water conducting collapse column in advance has been obtained.
