摘要:
正确的水文地质参数是准确预测矿井涌水量的基础。以实际抽水试验为基础,对比计算分析单孔抽水、一个观测孔和两个观测孔三种不同抽水试验方式下的水文地质参数,然后在考虑井损的情况下,对抽水孔的降深进行修正,以期得到更加精确的水文地质参数。结果表明,由于经验公式及井损的影响,使得单孔抽水所得参数误差及离散度较大,即使对降深进行修正后,单孔抽水依然得不到理想的结果。因此,建议采用两个观测孔的抽水试验方式来获取较为正确的水文地质参数。研究结果可为含水层水文地质参数计算及矿井涌水量预测提供理论依据,对矿井防排水系统设计和防治水措施制定具有重要现实意义。
Abstract:
It is the basis for mine water inflow forecast by using correct hydrogeological parameters. In this paper, based on the actual pumping test, a contrastive analysis on hydrogeological parameters from three different pumping test methods among single-hole pumping test, pumping test with one observation hole and two observation holes was conducted. Then, in order to get more accurate hydrogeological parameters, the single-hole pumping drawdown was modified by considering well loss. The results showed that the error and discrete degree of the parameters are larger even for the revised drawdown due to the influence of empirical formulas and well loss. Therefore, it was suggested that the method of pumping test with two observation holes should be used to obtain more accurate hydrogeological parameters. Consequently, the research results can provide theoretical reference for hydrogeological parameters calculation of aquifer, which also has directive significance to the waterproof and drainage system design of mine and the measures in water hazard control of mine.
