基于Aquifertest计算大海则矿井水文地质参数及涌水量

Calculation of Hydrogeological Parameters and Water Inflow Estimation of Dahaizei Mining Area Based on Aquifertest

抽水试验是一种在水文地质勘查中最为常用的水文地质试验,以榆林市大海则井田相关资料为依据,通过抽水试验,利用Aquifertest软件中的纽曼模型和博尔顿模型分别对水文地质参数进行确定,最终得出了相应的导水系数值为0.200 m^(2) /min、给水度值0.024、贮水系数值0.000177、渗透系数值4.434 m/d,并采用水平廊道法计算矿坑涌水量为大海则煤矿的涌水量为5169.351 m^(3) /d。此方法误差较小结果可靠,为快速高效地进行水文地质参数计算和涌水量预测提供一种有效方法,同时为后续矿床开采及施工建设提供参考依据。

Water pumping test is one of the most commonly used hydrogeological tests in hydrogeological exploration.Based on the relevant data of Dahaizei well field in Yulin City,this paper uses the Newman model and Bolton model of Aquifertest to determine the hydrogeological parameters,respectively.Finally,the corresponding drainage value is 0.200 m^(2) /min;water supply degree is 0.024;water storage value is 0.000177 and permeability coefficient is 4.434 m/d.Using the horizontal gallery method to calculate the water inflow of mine,the water inflow of coal mine is 5169.351 m^(3) /d.This method has small error and reliable results,which provides an effective method for calculating hydrogeological parameters and predicting water inflow quickly and efficiently,and provides a reference for the subsequent mining and construction of the deposit.
