摘　　要：总结整理了我国煤矿突水预警系统的发展现状,从顶板突水机理相关理论和突水危险性评价等研究结果出发,分析了煤矿顶板突水主要受到水源、覆岩地层、地质构造和采掘活动4种因素的共同控制,研究了顶板突水预警机制和顶板突水预警系统的建立,并介绍了灵东煤矿水文信息监测及顶板突水预警系统的建立和应用情况,建立了包括系统中心站和多个遥测子站的井上下水文信息监测系统,以煤系含水层水位下降情况为突水预警特征指标量值,设定了预警阈值,指导工作面防治水工作。The paper summarized the development status of the mine water inrush early warning system in China coal mines.From the study results of the related theory of the mine roof water inrush mechanism and the inrush danger evaluation,the paper analyzed the mine roof water inrush mainly jointly controlled by the four factors including the water resources,overburden strata,geological structure and mining as well as the excavation activities and studied the establishments of the roof water inrush early warning mechanism and the roof water inrush early warning system.The paper introduced the establishment and applications of the hydrological information monitoring and measuring and the roof water inrush early warning system in Lingdong Mine.A hydrological information monitoring and measuring system was established with the system central station and several remote measuring substation at the mine surface and in mine underground.Taking the water table dropping conditions of the aquifer in the coal base as the index value of the water inrush early warning features,the early warning threshold value was set up to guide the water prevention and control work of the coal mining face.
