摘要(Abstract)：

通过对某矿发生特大顶板突水工作面的充水条件分析,认为工作面采动叠加影响,在顶板厚层砂岩中形成的离层积水,是突水的主要充水水源。采用经验类比法和当量流径法,基于工作面涌水量值为正常涌水量与离层裂隙积水引起的涌水量之和,提出了涌水量预计计算理论公式,预计了该工作面未采区段恢复生产的涌水量大小。经实际开采检验,该方法基本可行。
Through the analysis of working face water filling conditions related to a mine having taken place super roof water inrush,this paper considered that the separated strata seeper from the influence of the repetitive mining action in thickly laminated sand was the main water filling source.The paper adopted experiential analogism and equivalent fracture method,the amount of working face water inflow was the sum of both normal water inflow and water inflow resulted from separated strata fracture seeper,in terms of the above,presented the theoretically computational formula of water inflow forecast,and forecasted the magnitude of resuming production water inflow in the virgin district of working face.The method checked by the actually mining action is basically feasible.
