摘　　要：为了精准预测煤矿采空区积水情况,减少因采空区积水情况预测不准确造成的钻探进尺浪费,防范因采空区积水情况预测不准确造成的顶水作业安全隐患及事故,基于目前煤矿采空区积水预测方法的局限性和斜沟煤矿生产地质情况及十多年来的防治水工作实例,通过观测涌出水量,计算涌入水量,确定储水构造边界、储水构造空间块段划分、块段水量和积计算、水量耦合及积水边界圈定等环节进行了试验研究和分析总结,得出煤矿采空区积水精准预测的方法及工作流程,经实践应用对比,研究得出的煤矿采空区积水精准预测方法预测精度高,指导的探放水工程效果显著,可供煤矿防治水工作者借鉴。In order to accurately predict the water accumulation in the mined-out areas of coal mines,reduce the waste of drilling footage caused by inaccurate predictions,and prevent safety hazards and accidents caused by inaccurate predictions,based on the limitations of the current methods for predicting water accumulation in mined-out areas,the production geological conditions of Xiegou coal mine,and more than ten years of water prevention and control work examples,this study conducted experimental research and analysis by observing the water inflow,calculating the water inflow,determining the boundaries of the water storage structure,dividing the water storage structure space into blocks,calculating the water volume of the blocks and the accumulation,coupling the water volume,and defining the boundaries of the water accumulation.The study derived the methods and work flow for accurately predicting water accumulation in the mined-out areas of coal mines.After practical application comparison,it was found that the accuracy of the predicted water accumulation in the mined-out areas of coal mines was high,and the effect of the guided exploration and drainage engineering was significant.This method can be referred to and applied by coal mine water prevention and control workers.
