摘要
通过对东欢坨矿区北部补给区的分析,研究了该矿的涌水特征。根据不同水平涌水量特征,分析了地面降水、开采长度、开采深度和涌水量的关系,建立了数学模型。利用有限元差分计算,预测了该矿不同水平的涌水量,结果令人满意且真实可信,为今后的井下防治水工作提供了可靠的理论依据。
Based on the analysis of the mining areas locates the northern supply area, the author studies the Donghuantuo Mine Water Inrush features. According to the different levels of water inflow characteristics, the author .analyzes the relationshipbetween surface precipitation, mining length, mining depth and water inflow, thus, establishes the mathematical model. By Using the finite element difference calculation, to predict the mine＇s water inflow in different levels, accordingly ,the results are satisfactory and true, and it makes the solid foundation for future control of mine water, meanwhile, it provides a reliable theoretical basis.
