大厂铜坑锌铜矿区4#风井工程地质评价

Engineering Geological Evaluation of 4 # Air Shaft of Dachang Tongkeng Zinc and Copper Mining Area

铜坑矿新建深近千米的4#风井,地质人员对该区构造破碎带、岩石稳固性等进行了初步预测,以此指导施工。风井竣工后,经过现场编录与原预测资料对比,发现两者基本接近。实践证明,重大工程项目在施工前进行地质条件预测和评价,能防患于未然,提高安全保障。

A new 4# air shaft of about 1 000 m deep is constructed in Tongkeng Mine. The geologists have carried out prediction of the tectonic fracture zone and rock stability of this area for directing the construction. After the completion of the air shaft, it was found that the site logging is almost the same as the previous prediction data. The practice has proven that the prediction and evaluation of geological conditions done before the commencement of the construction of major project are able to take preventive measures and improve security.
