矿产资源是人类社会的宝贵财富,是国家经济建设的重要物质基础。保护和合理开发利用矿产资源是国家一项极为重要的技术经济政策。因此,矿山企业生产的根本任务和最终目的就是充分合理地回收地下资源。众所周知,自然要素作为生产要素参加整个生产过程,这是矿产品生产的重要特点,因而矿山生产受无法控制的自然(资源)条件的制约。影响矿床(区)经济评价和资源合理开发利用的因素固然很多,但其中重要的一点就是矿石品位问题。实践证明,用于编制地质勘
Mineral resources are the precious wealth of human society and an important material basis for the country’s economic construction. To protect and rationally develop and utilize mineral resources is a very important technical and economic policy of the country. Therefore, the fundamental task of mining enterprises and the ultimate goal is to fully and reasonably recover underground resources. It is well-known that the participation of natural elements as a factor of production in the entire production process is an important feature of the production of mineral products. Therefore, the production of mines is constrained by uncontrollable natural (resource) conditions. Although there are many factors that affect the economic evaluation of ore deposits (districts) and the rational development and utilization of resources, the most important point is the grade of ore. Practice has proved that for the preparation of geological survey
