利用多井干扰法预算湖南省煤炭坝矿区矿井涌水量

Mine Inflow Estimating by the Use of Multi-well Interfering Method in Meitanba Mining Area,Hunan

在阐述煤炭坝矿区水文地质条件的基础上,利用势的叠加原理建立了水文地质模型,并以此建立了相应的数学模型。在各矿井多年排水量的基础上求出各矿井相对边界作用点的引用渗透系数Ki及Kimax,根据水文地质模型设计的已知的参数,将数学模型简化为多元一次方程组,进而求解得矿井开拓延深后矿区各矿井的涌水量。

Based upon hydrogeologieal conditions illustration, we established a hydrogeological model through potential field stacking, and thereupon a corresponding mathematic model. Through the use of mine inflow records in past years, referential permeability coefficients Ki and Kimax of each mine relative boundary points of application were calculated. According to the known parameters of designed hydrogeologieal model, simplified the mathematic model into multivariate system of linear equations, and then proceed to estimate each mine inflow after new levels are developed.
