查询词典 ore mining

Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。

Article 29 In mining mineral resources, a mining enterprise must adopt rational mining sequence and met hods and proper ore-dressing technique.

第二十九条开采矿产资源，必须采取合理的开采顺序、开采方法和选矿工艺。

Thissubject exerts the experiment method of analogue modeling, and we take geologic mining condition of the Xin Zhi Colliery of Huo Zhou Mineral Bureau in Shang Xi province as the physical model of background design. The experiment is divided into two phases, the first phase simulates the course of mining subsidence, we study rule of movement transmogrification of mining terrane. In the second phase, after the mining subsidence is gradually stabilization, we bring into bear different load in the different location of subsiding basin, and we study ground stability with goaf.

本课题以山西霍州矿物局辛置煤矿地质采矿条件为例，进行了相似材料模拟试验，试验分为两个阶段：第一阶段模拟开采沉陷过程，研究采动岩层移动变形规律；第二阶段在开采沉陷基本稳定之后，在沉陷盆地的不同位置施加大小不同的建筑物荷载，研究其地基的稳定性。

Image mining is the important branch of data mining.It is more than just an extension of data mining to image domain but an interdisciplinary endeavor.Image clustering and similarity retrieval are two basilic parts of image mining.

图像挖掘是数据挖掘的重要分支，它不仅仅是数据挖掘简单的扩展到图像领域，而是一个多学科交叉的研究方向周像的聚类和相似性搜索是图像挖掘的两个非常重要的领域。

Object of data mining is service concepts of service bag, carrier of data mining is history data, and spirit of data mining is mining classification.

在对服务概念开发进行数据挖掘时，服务包中的服务概念是数据挖掘的对象，历史数据是数据挖掘的载体，分类挖掘是数据挖掘的指导思想。

It realizes dynamic store and management of mining data and finishes inputting of mining data,3D visualization of mining area,establishing model of terrain surface,inquiring and analyzing spatial data,collection of DEM vector and image and so on.More convenience will be bring to mining manager.

系统实现了对矿业数据动态存储和管理，可完成矿业数据输入、矿区三维可视化、地形表面建模、矿区空间查询分析、DEM矢量影像数据集成等功能，必将给矿业管理工作者带来很大方便。

Based on the Knothe time function, the progressive prediction of surface subsidence due to underground mining was established, and the factor of proportionality describing the influence of geological and mining conditions was determined when there was no measured data in practice. A method of periodic pressure distance to divide the total working face into certain elements considering the mining rate or mining duration was proposed.

详细分析了单参数的Knothe时间函数、双参数的Sroka-Schober时间函数和Kowalski 广义时间函数的优缺点及其相互关系，建立了应用Knothe时间函数进行地表动态移动变形预计的原理、无实测资料矿井时间参数的确定方法和开采单元划分的周期来压步距法。

On the one hand, it helps to reduce the resistance of feudalization to the development of capitalist coal-mining industry, and to encourage the investment in coal-mining industry from businessmen, so there came a boom of investment in Shanxi coal-mining industry, and that promoted the prosperity of coal-mining industry.

一方面，有助于减少封建制度对资本主义矿业发展的阻力，进而鼓励商民投资矿业，此后山西出现了投资煤矿的热潮，带动了近代山西煤矿业的发展。
