补充资料:裂隙水
裂隙水 crevice water 岩石裂隙中的地下水。丘陵和山区供水的重要水源,矿坑水的重要来源。 裂隙水的形成和分布直接受裂隙成因的控制。按裂隙成因,分为风化裂隙水、成岩裂隙水和构造裂隙水。风化裂隙水埋藏在风化壳中密集、均匀、相互连通的风化裂隙网络之中,在一定范围内有统一的水力联系、统一的水面。风化裂隙水分布广,埋深不大,一般为10~50米,局部地区为100多米,易于开采,但水量不大,只能作为分散的山区居民生活用水或农业用水。成岩裂隙水赋存在岩石形成过程中产生的原生裂隙之中。沉积岩和火成岩中均可形成成岩裂隙。喷发岩中的玄武岩层,一般岩性硬脆,裂隙发育,张开性强。裂隙网络中往往形成强大的潜水流,当被地形切割时,常呈泉群涌出。当具有成岩裂隙的岩层被隔水层覆盖时,成岩裂隙水就成为承压水。如中国云南阿直盆地峨眉山玄武岩成岩裂隙水的水头高出地面17米。构造裂隙水赋存于岩石在地质构造运动中因受力而产生的裂隙之中。构造裂隙水按产状又分层状水和脉状水。层状构造裂隙水因各组裂隙相互切割,形成统一的含水层,一般分布均匀,水量不大。脉状构造裂隙水是埋藏在断层破碎带或接触破碎带中的地下水。这种裂隙水往往汇集周围透水性较差的层状构造裂隙水,水量较大,具有局部承压性质。矿坑遇到这类裂隙水,可造成突然涌水甚至淹矿事故。裂隙水的运动在多数情况下符合达西定律;在少数大裂隙中的水不符合达西定律,甚至变为紊流运动。 |
