摘要
从水力学中的伯努里 (DanielBernoulli)方程出发 ,考虑水流的水头损失 ,推导出一种井下探放水钻孔涌水量计算的新方法。结合历年防治水实例验算 ,该公式计算精度高 ,与实际吻合好 。
Based on Daniel Bernoulli equation in hydraulics,consider the water head loss of flow,deduce a new method of surveying under ground drill hole water_make.Combined with water prevent and cure practical calculation every year,show the calculation precision of this formula is high,and it's suitble for practice and has great usable value.
