Excessive exploitation of groundwater in Ordovician limestone is the key reason for the formation of ground fissures.

在调查分析地裂缝时空分布特征的基础上，研究地裂活动与区内水文地质条件、地下水开采过程的关系，认为过量开采奥灰水是产生地裂缝的主导因素。

Article 22 Any entity exploiting mineral resources shall make a comprehensive plan, set forth a reasonable development and use scheme, and take proper exploiting sequence, methods and ore dressing processes.

第二十二条开采矿产资源，应当统筹规划，制定合理的开发利用方案，采用合理的开采顺序、方法和选矿工艺。

It is inevitable to exist excessive water in the crude oil in the late exploitation of many outdate oil field and exploitation on the ocean flat. It is not valid to process oil very well without dealing with crude oil. It is necessary to have water-oil separation equipments for purifying and separating crude oil. Meanwhile, it is necessary to dispose oil from sewages to reach the national standard in the industrial sewage treatment, and the water-oil separation equipment is urgent need too.

在我国众多老油田开采的后期，以及海上石油平台的原油开采中不可避免的存在原油含水量较大，不经过处理无法有效的对石油进行深加工，亟需有效的液液分离设备对原油进行提纯和分离；同时在工业污水处理中也经常需要将废水中含有的油类去除以达到国家排放标准，这同样需要有效的液液分离设备。

Influences of overlying strata failure height of different exploitation methods, programs and geography terms are analyzed.

分析了不同开采方法及开采程序、不同地质条件对覆岩破坏高度的影响。

The Star Fold was first explored by fringe-space mining operations, happy to drill, pack, and sleep back.

人们第一次发现The Star Fold是在边缘宇宙开采行动时，工人们愉快的开采、装箱，长远的路途还保证了他们在回去时可以得到充足的睡眠。

As the main base of phosphorite mine in Guizhou Province,the exploitation scope expanding of Wengfu phosphorite mine has had a great impact on the ecological environment.

由于贵州省磷矿具有埋藏浅、易开采、质量高的特点，其磷矿主要采用露天开采的方式，对磷矿山生态环境的破坏程度极大。

The system adopt the method of fast establishing new project based on template file; to forecast the ground movement and deformation of multiple random-shape faces according to probability integral principle, designs the new algorithm of drawing section plane and the new calculation of area and volume of subsided section based on isoclines, at the same time, gives the rule of classifying mine surface damage under GIS environment on the basis of GIS uncertainty theory.

由于开采沉陷过程具有时空特性，本文基于Mapinfo6.5开发了矿区地表变形预测与可视化系统（Mine Surface Deformation Forecasting and Visualization System，简称MSDFVS）系统采用以模板文件形式快速建立新项目的方法，运用概率积分法进行任意形状多工作面开采沉陷地表移动与变形预计，基于等值线设计了新的剖面图绘制算法和塌陷区面积、体积的计算方法，并结合GIS不确定性理论提出了GIS图形环境下矿区地表塌陷破坏等级划分准则。

This paper studied the plotting of the hazard zone of Wulong mine's rockburst. This paper used ANSYS program to set up model then put up stress analysis. Taking the 311 working face of Wulong coal mine as an example, the contours of vertical stresses in the roof and floor are obtained corresponding to the mining distances of 100 m ,200 m ,300 m and 400 m respectively.It is indicated that the magnitude of vertical stress is the important influencing factor of rockburst.

用ANSYS建立模型进行应力分析，通过模拟开采3311，3l1，213工作面得到了推采距离为100、200、300及400 m 时的顶底板y向应力等值线图，指出顶板y 向应力大小是判断冲击地压是否发生的重要因素，当开采l00 m 和400 m 时工作面迎头位置产生高应力集中区，极易发生冲击地压事故。

Using three prediction methods—probability integral, DM (1, 1) model and exponential smoothing and field measurements analyze the prediction accuracy and point out the applicable condition of the models.

对地表移动研究的核心内容——预测技术，本文提出应用多层递阶周期项分析方法分析由开采引起的地表移动，认为由开采引起的地表移动是趋势项、周期项及随机项运动的合成。
