摘要
单位涌水量是评价煤矿区含水层富水性强弱和划分矿井水文地质类型的重要指标之一。分析了单位涌水量换算的意义及煤矿钻孔实际抽水资料,研究了具有三次降深、二次降深及一次降深资料单位涌水量换算的方法,结合某煤矿的实际抽水资料进行了验证,计算结果符合该煤矿区含水层富水性的实际情况。
The specific capacity can evaluate the water rich property of aquifer and divide the hydrogeological typeof mine water, we analyze the significance of conversion about specific capacity. Besides, we explain the method ofusing the Q–S curve equation to converse the pumping test data of three times, and how to deal with the data of oneor two times drawdown. At last, the method was verified by use of the actual data of a coal mine, and the results arein accordance with the actual situation of the water rich property of aquifer.
