| 摘 要： | 矿井水害是威胁煤矿安全生产的重要因素之一。在分析煤矿水文地质参数、含水层特征及煤层特征及煤矿开采特点的基础上,选取相关分析法进行矿井涌水量预测。利用数理统计皮尔逊相关系数分析矿井涌水量与其相关因素之间的密切程度,选取SPSS软件建立了矿井涌水量与煤炭产量、掘进进尺及工作面断面面积之间的相关关系;建立矿井涌水量预测方程,并进行了精度预测,得出该矿井的涌水量为145.85 m 3/h。相关分析法在矿井涌水量方面简单有效、可行性强,具有很高的推广价值。

| Abstract: | Mine water disaster is one of the main factors threatening coal mine safety production.Based on the analysis of mine hydrogeological parameters,aquifer characteristics,coal seam conditions and coal mining characteristics,the correlation analysis method is selected to predict the mine water inflow.By using Pearson correlation coefficient of mathematical statistics,the closeness between mine water inflow and its related factors is analyzed,and the correlation between mine water inflow and coal output,driving footage and working face section area is established by using SPSS software.Through the establishment of mine water inflow prediction equation and accuracy prediction,the mine water inflow is 145.85 m 3/h.The correlation analysis method is simple,effective and feasible in the prediction of mine water inflow,which has very high promotion value. |
