摘　　要：顶板离层水水量的预测及水源位置的确定是解决工作面离层水涌水的技术关键.在实测红柳煤矿1121首采工作面顶板涌水量及理论分析顶板涌水的机理之上,提出了该工作面集中涌水的水源为工作面顶板离层水,并总结分析了顶板离层水的形成机理和制定了相应的防治水措施.根据工作面周期涌水量和实际离层水疏放情况预测了离层水积水量,据此提出了红柳煤矿1121工作面顶板离层水探放方案,并在现场进行了成功应用.The key technology of solving abscission layer of water gushing water in working face is the prediction of roof abscission layer of water and water positioning. Working face of roof abscission layer water is the water positioning was put forward based on the field measurement of roof flowing in 1121 was first working face and theory analysis roof flowing mechanism. Formation mechanism of roof abscission layer water was analyzed and measures of prevention and control of water were made. A explore put scheme of roof abscission layer water in 1121 working face in Hongliu mine was put forward according to the forecast of abscission layer of water product based on the cycle flowing and field emissions in working face. The application is successful in the field.
