Based on the existed features of parallel ore bodies in the Zhangfushan district using a physical modeling method, the reles of surface subsidence and rock movement during underground mining process in the Jinshandian iron ore mine are studied and predicted.

On the basis of major ore-controlling macro-condition and mineralization micro-information,gold-bearing nature of the complex rock in Jinshandian is evaluated,which has furnished an illustration to the analysis combining heavy sand with geochemistry.

Technology research on underground ventilation cooling in Jiudian gold mine

Based on the actuality of underground mining system in Jiudian gold mine,the mined-out areas were used as assistant air exit and it achieved good result.

Dianfang gold deposit is located at the east part of the Machaoying fault zone, andhosting in the south contact of an explosive breccia chimney, Xionger Group.
