建国初期兴建的一批矿山,经过30多年的生产,现在已相继到了开采后期,有的按设计规定已临近闭坑期。但在此情况下,能不能使矿山延长寿命?这是一个非常值得研究的问题。因此,必须加强矿山地质工作,建立相应的矿山地质工作程序,把矿山地质工作在为采掘服务同时,开展矿床综合研究— A group of mines built in the early years of the founding of the People’s Republic of China, after more than 30 years of production, have now reached the latter part of the mining period. Some of them have approached closed pits according to design regulations. However, in this case, can we extend the life of the mine? This is a question worth studying. Therefore, we must strengthen mine geology work, establish corresponding mine geology work procedures, and work on mine geology for extraction services, and carry out integrated research on deposits—
