摘　　要：在深入研究我国煤矿顶板透水发生及其成功控制案例的基础上,对顶板透水事故发生的原因、实现的条件及其动力信息基础进行了系统研究,以此为基础提出了顶板透水事故预测与控制的方法。针对淮南矿业集团谢桥煤矿1122(3)工作面,分析了谢桥井田地质及水文地质特征,并根据钻孔及井下资料,研究了顶板砂岩、粉砂岩运动规律。以实用矿山压力控制理论为指导,建立顶板控制信息动力决策模型,着重探讨了导水裂隙带和斑裂纹对顶板砂岩透水的影响机理。Based on the in-depth study of cases of water-inrushing from roof that were successfully controlled in coalmines in China, this paper makes systematic study on reasons of water-inrush from roof, conditions of disaster and the basic information of stratum movement and mechanics. The method of predicting and controlling water-inrush from roof ispresented. For the 1122 （3） Workface of Xieqiao Coal Mine in Huainan Mining Group, analyzed geological and hydrogeological characteristics of the Xieqiao Coal Mine, and in accordance with bore and underground information, studied the movement of sihstone and sandstone of roof. According to the utility ground pressure control theory, established the roof control information dynamic decision-making model, discussed the impact of the water fracture zone and crack on water-inrushing from roof. Correctly predicted and controlled the incident of water-inrushing from roof, and avoided the mine flood accidents.
