Quarries often fill with water, from either rain collection or from the passing of the groundwater table during extraction, which then must be pumped out. The three main types of rocks which are commonly extracted by a quarrying method are igneous, metamorphic and sedimentary types of stone. These stones are quarried for various purposes ...
