摘　　要：煤矿井下采空区积水是当前煤矿井下的主要隐蔽致灾因素之一,而由于其形状的不规则性往往难以准确预计采空区的起伏变化和积水情况。本文提出和设计了采空区标高数据曲面拟合系统,充分利用现有的采空区测点资料进行建模拟合,为煤矿井下采空区空间分析和积水量预计提供了科学的分析方法。Water accumulation in goaf is one of the main hidden disaster causing factors in coal mine. Due to its irregular shape, it is often difficult to accurately predict the fluctuation and water accumulation in goaf. This paper designs a curved surface fitting system for the elevation data of the goaf, which makes full use of the existing data of the goaf survey points to model and fit, and provides a scientific analysis method for the spatial analysis of the goaf and the prediction of water accumulation in the coal mine.
