The biggest concern of pumping out water from this deep is the gradual settling down of the landsurface.
从这么深的地方抽水,最大的问题是地表会逐渐下沉。

If the water table intersect the landsurface, groundwater will flow out onto the surface at springs, whether to be collected there or to subsequently flow farther along a drainage.
如果地下水位与地表相交,地下水将在泉水处流出地表,聚集于此或是随后沿着排水系统进一步流动。

It has been estimated that an additional one-fourth of the Earth's landsurface is threatened by this process.
