摘　　要：在对某矿含水层富水性、地质构造、隔水层等影响底板突水因素综合分析的基础上,采用突水系数法和安全水头压力值对4号煤层底板主要灰岩含水层突水危险性进行了评价,分析结果表明,伏青灰岩水对-550 m标高以下4号煤层的开采具有突水危险性,而对其他含水层均不构成突水威胁,这为矿井防治水和安全生产奠定了理论基础.Based on analysis of water yield properties of a certain coalmine such as floor confined aquifer, geologic structure, aquifuge and other factors, the paper evaluates water bursting hazard of main limestone aqui- fer-beds under No. 4 coal seam floor through water bursting coefficient method and safety head pressure. Resuits show that other aquifer-beds have no threatens for No. 4 coal seam besides Fu-qing limestone with water below -550 m. The work lays a theoretical foundation for the safety in coal mines.
