摘要
个旧矿区位于红河和南盘江两大水系的分水岭地带,属岩溶中山地貌,岩溶洼地、漏斗、落水洞等星罗棋布。矿区内无地表河流,地下水主要接受大气降雨补给。矿坑涌水量主要受大气降雨、岩溶发育程度、断裂构造及隐伏岩浆岩体控制。
The Gejiu orefield is a Sn muhimetallic ultra - large orefield. It is in the SE area of Gejiu city and in the water shed area between Honghe river and Nanpanjiang river system. The geomorphology of it belongs to the karst middle mountains type, with many karst depression, funnel and sinkhole, etc, spread all over the area. The main strata in the area are T2g carbonate rock and the buried magrnatie rock. There isn＇t any surface river in the orefield. The underground water is supplied mainly by the air precipitation. And the welling capacity of tunnel is controlled mainly by air precipitation, karst development, fault structure and buried magrnatic rock body.
