利用冲洗液消耗量求水文地质参数

Using Wash Water Quantity of Geological Log to Calculate Hydro-geological Parameter

为了获取东滩煤矿二迭系3煤顶板砂岩含水层水文地质参数,在水文地质资料极少的情况下,通过对大量地质钻孔资料的分析对比,找到了钻孔冲洗液消耗量与抽水孔水文地质参数之间的相关关系,建立了相关方程。利用相关方程求出了全东滩矿3煤砂岩顶板含水层的水文地质参数。计算结果与实际突水点资料的对比表明,求得的水文地质参数具有一定的实用参考价值。

For the purpose to get the hydro - geological parameters of Triassic age coal bed 3 of Dongtan Coal Mine, the author analyzed geological and drill log materials, under the condition of being short of the hydro - geological material, found the relationship between wash water quantity in geological log and the hydro -geological parameters, and set up their correlation equation. The hydro - geological parameters of Triassic age coal bed 3 of Dongtan Coal Mine be calculated with it. The comparison of calculated results with the actual data of water irruption quantity showed that the calculated hydro - geological parameters are of practice value.
