在矿井水文地质类型划分工作中,评价受采掘破坏或影响的含水层及水体的富水性时,需要对原始抽水试验资料进行口径91 mm、抽水水位降深10 m为准的单位涌水量换算。但目前换算方法中存在着一些问题,在对这些问题做分析和讨论的基础上,提出了一种应用Matlab数值分析软件进行最小二乘法曲线拟合的单位涌水量换算方法,并结合实例计算证明了该方法的可行性。该方法可减少换算过程中的人为因素产生的误差,使得换算结果更加准确,为今后的生产实践提供了参考。最后对该方法的实际应用提出了一些建议。
In the classification of mine hydrogeological types, when assessing the water-richness of aquifers and water bodies damaged or affected by excavation, it is necessary to convert the raw water pumping test data into units of gushing water with a caliber of 91 mm and a pumping water level of 10 m. However, there are some problems in the current conversion methods. Based on the analysis and discussion of these problems, a method for calculating the inflow data of units based on least squares curve fitting using Matlab numerical analysis software is proposed. Combining with the examples, The feasibility of this method. The method can reduce the error caused by human factors in the conversion process and make the conversion result more accurate, which provides a reference for future production practice. Finally, some suggestions are put forward for the practical application of this method.
