不久之前,对矿床勘探和采矿企业设计中矿石工艺性质变化问题还没有给予应有的重视。工艺样品是按矿物种类和组份的平均含量采取的。这样往往不能可靠地评价矿石沿矿体走向和倾向的变化。设计时,未注意矿床不同地段和不同矿体以及各开采期间矿石各种工艺品级比例的变化情况。在大多数黑色和有色冶金企业中,上述缺点造成了设计指标和实际指标之间的巨大差别。这就给企业编制工作计划带来了极大的困难,降低了该企业工作的经济效益。 Not long ago, no attention was paid to the change of the nature of the ore process in the design of deposit exploration and mining enterprises. The process samples are taken based on the average mineral species and components. This often can not be reliably evaluated ore along the trend and tendency of ore body changes. At design time, no attention has been paid to the changes in the proportions of various handicrafts of ore at different locations and different ore bodies in the deposit as well as during each mining period. In most ferrous and non-ferrous metallurgical companies, these shortcomings create a huge difference between design and actual metrics. This has brought great difficulties to the preparation of work plans for the enterprises and reduced the economic benefits of the work of the enterprises.
