补充资料：地表钻孔抽水
地表钻孔抽水
dewatering through well
d{bjoo之uankong ehoushu}地表钻孔抽水(dewatering through well)为了解除矿区地下水害威胁，在地表矿区边界之外的来水方向上围绕矿体开凿若干个大直径钻孔，在钻孔内安放深井泵或潜水泵排水，使矿区开采地段处于疏干降落漏斗水面之上的疏干方法。钻孔布置见矿山深井降水孔平面图。钻孔直径D可按公式D一d十50+2 了尸·、’· 户。’\。。/ 望‘，卜’。 户)’力价 /{/。一、\ 匕一办’\ 矿山深井降水孔的平面图 l一来水方向;2一抽水钻孔; 3矿区;4一隔水层(a十b)计算。其中d为水泵的最大外径，mm;。为过滤管的厚度，mm;b为充填料的厚度，mm。地表钻孔抽水疏干在地表进行，施工简单、方便，劳动条件好、施工管理容易，钻孔的布置及疏水设备的迁移都比较灵活。因此，在条件允许的情况下，应该尽量采用地表钻孔抽水，疏干矿床。 (张福有)
