Lanping Pb-Zn mines of YunNan province is the biggest Pb-Zn mine of China. However, every produce tache is in aboriginality, so it is necessary for the mine to digitaled.

云南兰坪铅锌矿是我国最大的铅锌矿，但是各个生产环节还都处于原始状态，所以对该矿山进行数字化是相当必要的。

Combining these two theories, we advance some advice about the usage of grinding machine and the active mechanism of aidant grinding dosage.

综合两种理论对助磨剂在磨矿过程中的作用机理，进而提出对助磨剂的使用及磨矿过程的几点建议。

Aidant grinding dosage will improve grinding effect, so the research on aidant grinding dosage is of great significance.

磨矿过程中使用助磨剂会提高磨矿效率。

In grinding, changing the liquid of grinding dosage will improve grinding rate, and the selection of aidant grinding dosage shall start from dispersive aidant grinding dosage.

磨矿作业中，每隔一段时间更换助磨液会提高磨矿效率；在筛选铁矿的助磨剂时，应从分散类助磨剂中入手挑选。

Coal Mine,the transformation reasoms and plan of the central air shaft are analyzed.

文章依据刘桥一矿采掘接替，分析了刘桥一矿中央风井改造的原因、改造方案，以及中央风井改造后的通风系统优化。

The results of XRD showed that as-prepared films were not only in anatase state but also in brookite.

结果表明：纯TiO2薄膜中，TiO2不仅以无定型态存在，而且还以板钛矿和锐钛矿的形式存在。

The results show that the pure TiO2 thin film composed of not only amorphous but also brookite and anatase.

结果表明，纯TiO2薄膜中，TiO2不仅以无定型态存在，而且还以板钛矿和锐钛矿的形式存在。

There are three types of TiO2 crystalline: anatase, rutile and brookite.

用作光催化剂的主要是锐钛矿型和金红石型，且其中以锐钛矿型的催化活性最高。

Seismic methods for mineral exploration have been applied into more fields than just ore body itself, and the large deepseated structures, such as orecontrolling structure, alteration zone, and key lithologic layer have become the targets of indirect seismic exploration.

金属矿地震找矿的应用范围得到了扩展，不再局限于矿体本身，控矿构造、蚀变晕、重要岩性层等大型深部构造单元成为了地震间接找矿的目标体。

In the mine of Ruashi, about 20 kilometres outside Lubumbashi, around 4,000 miners, some as young as eight, dig and sieve from dawn to dusk.

在卢本巴西外20公里左右的RUASHI矿，有大概4000名矿工，有的只有8岁大，从早到晚挖矿筛矿。
