通过对广西某石灰岩矿区水文地质条件的分析,对该水文地质单元的水文地质模型进行概化,推导出了定水头补给半无限带状含水层中完整井流公式,并运用该公式对开采条件下矿坑涌水量作了评价。最后,运用传统的逐个干扰井叠加法对该公式的评价结果进行验证,结果表明,当映射叠加次数足够多时,其计算结果极为相近。但就其计算方法而言,映射叠加方法较为繁琐,而运用该公式计算则显得较为方便。
By analyzing the hydrogeological conditions of a limestone mining area in Guangxi and generalizing the hydrogeological model of the hydrogeological unit, a complete well flow formula in the semi-infinite belt aquifer with fixed head recharge is deduced. Based on this formula, Under the pit water inflow was evaluated. Finally, the result of this formula is verified by the traditional superposition method of interference-by-interference wells. The results show that the results are very similar when the number of superpositions is enough. However, in terms of its calculation method, the mapping superposition method is more complicated, and the calculation using the formula is more convenient.
