摘　　要：唐安煤矿3401工作面的生产安全受到顶板涌水的威胁,为解决此类问题通过数值模拟、理论分析及计算等方法对顶板水害机理及防治技术进行研究,确定工作面回采引起的导水裂隙带高度为93m,工作面上覆岩层含水层静态中储量为84.3万m3,预测3401工作面最大的涌水量为789m3/h,据此对3401工作面的采前顶板疏放钻孔和回采过程中排水设施进行设计,3401工作面回采期间实际涌水量最大为750m3/h,设计的水害治理措施应用效果良好,保证了3401工作面的安全正常回采。Tang An safety production in coal mine 3401 working face under the threat of roof water,in order to solve this problem by numerical simulation,theoretical analysis and calculation method for roof water damage mechanism and to study the prevention and control technology,determine the mining face caused by the water flowing fractured zone height is 93 m,the working plane reserves of 843000 m3 in the overburden rock aquifer static,predict 3401 face the biggest water inflow of 789 m3/h,on the basis of the 3401 working face in the process of mining roof ShuFang before drilling and mining drainage design,3401 mining face during the actual location of the maximum is 750 m3/h,The designed water damage control measures have good application effect and ensure the safety and normal stoping of 3401 working face.
