摘　　要：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 mine hydrogeological division work, when the aquifers and water affected or damaged by mining are evaluated, a unit -flow conversion needs to be worked out to transfer the original data to the condition that diameter 91mm,drawdown 10m. However, there are some problems with the method process. On the basis of the analysis and discussions on these issues, we present a new con- version method based on curve fitting using Matlab. And through practical calculations,we proved this new method available. Conver- sion error caused by human factors can be reduced in the process of the conversion and the conversion results more accurate, which would provide a reference for future practice. Finally the article gives some suggestions about practical application of the new method.
