赣杭铀成矿带大洲矿田层状火山熔岩型铀矿资源评价

摘要

本文全面总结了大洲铀矿田成矿地质背景及铀矿特征，分析了溶浸采矿条件，论述了大洲铀矿田溶浸采矿的可行性，并指明应用溶浸采矿技术重新评价赣杭铀成矿带硬岩型铀矿资源的必要性。%According to the technological requirements, using theory ofsolution mining, the author makes a resources evaluation of layer-shaped volcanic lava-type uranium deposits in Dazhou ore-field, Gan-Hang uranium metallogenic belt. This paper comprehensively summarizes the metallogenic geologic background and characteristics of uranium deposits in Dazhou uranium ore-field, analyses the conditions of solution mining and describes the feasibility of solution mining in Dazhou uranium ore-field, then proposes the necessity to reevaluate hard rock uranium resources in Gan-Hang uranium metallognic belt.
