废石

Oe the basis that stockpiling low grade ore necessitates the expense of rehandling, process the low grade ore directly from the pit, thus freeing up potential storage volume for waste rock.

在储蓄低等级矿石成为直接从矿坑中直接处理，加工这些矿石的必要一节后，要尽可能的寻找跟占用空间来处理废石。有些意思是猜的。

Zhang's old village is almost impossible to reach because of an endless stream of identical red lorries trundling along the one-lane mountain road, carrying construction supplies and removing debris.

要到达张所居住的古老村庄几乎难以办到，因为在通往该地的单行山路上，鲜艳的红色卡车绵延不绝，运来建筑物资、运走废石瓦砾。

If according to traditional method of exfoliate alkali, not only increase waste stones but also make more than 10 million tons mine rock useless. Economy and environment will be greatly distorted.

若按传统剥离除碱方法，不仅会大量增加废石排放，还将使1000多万吨低品位矿岩不能利用，其经济和环境损失严重。

After combining LanYingXu stope, the practical problems have found in augment production stripping-ratio and lower conveying capacity of augment barren rock . The detailed study have been done to control the production stripping ratio ,the economic stripping ratio and optimal limit depth in the exploitation of middle and bottom LanYingXu stope .The economic mathematical model has been established and the application has been built in windows visional system. The optimal result can offer the referenced. Basis for mining production ,for organization and management.

并根据兰营徐统一采场后，生产面临的剥采比增大、废石运量增加、运输能力降低、露天开采深度越来越大的生产实际问题，对兰营徐采场中深部开采的生产剥采的控制、经济合理剥采比及最终开采深度进行了详细的研究，建立了经济数学模型，并编制了Windows环境下的可视化的应用程序，计算出了优化结果，为矿山生产、组织管理提供了参考依据。

At present, the multipurpose use of gangues and tailings retrieved useful elements and material transferred at home and abroad.

在富矿资源日益减少的今天，贫矿资源、废石及尾矿等非传统资源的开发利用越来越受到重视。

In pace with high-grade ores reduced, development of low grade ores, gangues and tailings becomes more and more important.

在富矿资源日益减少的今天，贫矿资源、废石及尾矿等非传统资源的开发利用越来越受到重视。

The manual mineral deposits are the gangues and tailings which can be re used.

&人工矿床&主要是指废石及尾矿等能被重新利用的资源。

Article 36 A mining enterprise shall adopt scientific mining methods and techniques for mineral separation so as to reduce the production and storage of gangues, waste rocks, mullocks and other mining solid wastes.

第三十六条矿山企业应当采取科学的开采方法和选矿工艺，减少尾矿、矸石、废石等矿业固体废物的产生量和贮存量。

In the future, further reducing the size of ore fed into mill and pre-taking out a part of waste rock before feeding ore into mill are the trend of development of ore grinding technology.

进一步降低入磨粒度，同时预先抛出部分废石提高入磨品位将是今后的发展方向，因此开发超细碎工艺非常有必要。
