开源节流 延长矿山寿命

湖南的多数矿山,因开采年限较长,资源耗竭而濒于闭坑,部分老矿山将难以维继。为缓解这种严峻局势,延长矿山寿命,本文提出以下对策:①抓紧矿山勘探,摸清矿区资源;②矿、队联合勘查,扩大外围矿量;③加强矿山管理,充分利用资源;④改进选矿工艺,综合回收资源。并据实例阐述了这四点看法。

TAPPING NEW RESOURCES AND ECONOMIZING ON EXPENSES,PROLONG THE LIFE OF MINES

Most of the mines in Hunan province are on the verge of closing down due to exhaustion of resources in the long period of service, some of which are difficult to be maintained. In oreder to ease up the severe situation and prolong the life of the mines, following countermeasures are proposed in this paper: 1). Pay close attention to the prospecting of the mines so as to ascertain the reserve of the mines; 2). Expand the ore reserves in the outskirts through co-operative exploration between mines and geologic teams; 3). Enhance the management of the mines and make full use of the resources; 4). Improve the ore-dressing technology so as to make comprehensive recovery of the resources. The above four opinions are explained with real examples in the paper.
