矿井单位涌水量比拟法在矿井涌水量预测中的应用

通过对风水沟煤矿矿井历年疏干排水资料的统计分析以及特征的研究,结合矿井水文地质条件,建立了不同开采水平、开拓面积的矿井单位涌水量比拟法计算公式,并对矿井的一、二采区的涌水量进行了分析预测。结果表明,矿井单位涌水量比拟法计算公式预测的2007、2008和2009年涌水量与实际疏干排水量之间的误差分别为6.5%、8.7%和7.9%,预测精度较高,值得借鉴推广。

Application of Mine Specific Capacity Analogue Method in Mine Water Inflow Prediction

Through statistical analysis and characteristic study of dewatering data over the years in the Fengshuigou coalmine,combined with mine hydrogeological condition,have established mine specific capacity analogue method formulae for different gallery levels and development areas.On these grounds,have carried out analytical mine inflow prediction for Nos.1 and 2 winning districts of the coalmine.The results demonstrated that,predicted mine inflow of 2007,2008 and 2009 through the mine specific capacity analogue method compared with actual drainage discharge capacity,the errors are 6.5%,8.7% and 7.9% respectively,thus the prediction accuracy is rather high,and worthwhile reference and popularization.
