焦作矿区是我国著名的大型岩溶水充水矿区，底板突水灾害严重．介绍了突水源、突水强度与突水点的分布特征，阐述了矿压与突水、矿井充水程度与突水水压及隔水层及突水的关系．从突水地点、突水时间、突水量和突水危险度４个方面提出了评价和预测突水的新方法． Jiaozuo Mining Area is a well-known large-scale karst water-filled mining area in China with serious water inrush from the floor. The distribution characteristics of water inrush, water inrush intensity and water inrush point are introduced. The relationship between water pressure and water inrush, the degree of water filling in coal mines, water inrush pressure, water barrier and water inrush are described. A new method of evaluating and predicting water inrush was proposed from four aspects of water inrush location, water inrush time, water inrush and water inrush hazard.
