水口山矿务局柏坊铜矿是一个背负沉重亏损包袱的百年老矿，自从 1998年底青年矿长张登南走马上任以后，通过内抓管理挖潜力，外拓市场创效益，使百年老矿在短短的一年时间里便焕发出勃勃生机，一举扭转了企业的亏损局面。 1999年，全矿完成铜精矿含量 2560吨，为年计划的 142.2 Baokou Copper Mine of Shuikoushan Mining Bureau is a hundred-year-old mine with a heavy loss burden. Since Zhang Dengnan, the young mine director, took office at the end of 1998, he managed to dig potentials through internal management and created profits through the extension of the market, making the 100-year-old mine short. In one year, it will be full of vigor and vitality, reversing the company’s loss situation. In 1999, the whole mine completed 2560 tons of copper concentrate, which was 142.2 years of the plan.
