工作面

Therefore both from technical and economic points of view, the powered support is a very important piece of equipment in a long wall face.

因此，从技术和经济两方面的观点看，液压支架是长壁采煤工作面设备中十分重要的一部分。

The study we have performed demonstrated that the main roof first broke with asymmetry character; gully mining-induced slope was divided into multilateral blocks by surface advance cracks. Furthermore, multilateral blocks rotated and subsided by the function of extrusion and friction between the broken rock block above the goaf and the rock mass advance the coalface.

冲沟坡体下开采时，基本顶初次破断具有不对称性；冲沟采动坡体被地表超前裂隙切割成多边块状，并在两侧坡体的夹持摩擦作用下缓慢回转下沉；相同地质条件下，坡角越大，采动坡体对工作面矿压影响越大。

Adopt the coal work usually face to adopt the empty area gas is to be a kind of wastes to is throw away,But we need only to make some engineerings slightly to be it to a kind of public fuel or chemical engineering raw materials then.

采煤工作面采空区瓦斯通常是作为一种废弃物被丢弃，而只需稍作一些工程即可将其作为一种民用燃料或化工原料。

Considering the current state of gas drainage in goafs of highly gassy mine in China, the "draining while mining" gas drainage method during open region movement behind working faces was emphasized to raise the resource recovery, decrease atmosphere pollution and implement gas control.

针对我国高瓦斯矿井采空区瓦斯抽放的现状，强调了在工作面后方&边采边抽&的开区移动瓦斯抽放方法，以提高资源回收减少大气污染与瓦斯治理的双重效益。

Deep drawn parts offer the ability to pre-plate the internal working faces with gold, while also work-polishing and hardening the wall to optimize product lifetime.

深冲部件提供了对内部工作面镀金的能力，还可以在工作时抛光和硬化壳壁以延长产品寿命。

Coal and gas outburst;ground stress;heading face; finite element method; ANSYS

煤与瓦斯突出；地应力；掘进工作面；有限元；ANSYS

On the surface, the symptoms of these two cases are not cut surface perpendicular to the face, the same machine and the knife for cutting in length.

表面上，这两例的症状都是裁切面不能正常垂直于机台的工作面，同一刀的裁切品中长度不一。

Not only must have the crisis management consciousness, must grasp the risk management the concept and the content, but also must melt into these skills to in the daily responsibility and the motion, thus in its enterprise or own working surface machine-hour, can be calm on the point of death should to, wins the survival the opportunity.

不仅要有危机管理意识，更要掌握风险管理的概念与内容，还要把这些技巧融入到日常的职责和行动中去，从而在其企业或自身工作面临危机时，能从容应对，赢得生存的机会。

It is a complicated problem involving several of subjects such as geology, coal mining, rock hydraulics and rock crack mechanics.

采煤工作面底板突水是涉及煤矿地质学、煤矿开采学、岩体水力学和岩石断裂力学等学科的一个比较复杂的问题。

Based on the theoretical analysis for 1000 m long drainage skills, the UDEC4.0 numerical simulation software is adopted to perform the calculation, showing that the height of caving zone and fractured zone of gob is 9 m and 30 m, the vertical height from the mining induced O-shaped circle to the roof is 10~25 m, and the horizontal distance to both sides of gob is 10~35 m.

本文在顶板千米钻孔抽采技术原理分析的基础上，采用UDEC4.0数值模拟软件计算得出采空区冒落带和裂隙带高度为9m和30m，采动裂隙&O&形圈的范围为距工作面顶板垂高10~25m，距采空区两侧水平距离为10~35m。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
