采煤工作面

The case of inclined longwall and overhead mining at 31005 face in Zaozhuang Coal Mine and technical manage measures are introduced.

介绍了查庄煤矿在31005工作面使用倾斜长壁仰斜开采的情况及技术管理措施，对相似条件下此类采煤法的使用提供了可借鉴的经验。

After analyzing and generalizing the data of mining sewage of two testing workingfaces 7303,7305 of +600 level in Wuyang coal mine of Qinshui coalfield, this paper calculates the corrupted under ground water dynamic and static modulus, then combines them with the hydrogeology conditions to work out the water yield of Shanxi formation gritstone.

在对沁水煤田五阳矿区+600水平7303，7305两个试验工作面开采面积及排水资料进行归纳总结后，计算了采煤破坏的地下水动模数及静模数，并结合矿区地质及水文地质条件，计算了山西组砂岩的给水度。

Through the combined reform of the outer spaying of the coal cutter,the spraying of the beare,the spra- ying of the transfer spot and the Water curtain,which induce the dust concentration,the job condition has been im- proved and has reaeched the preceptorial purpose to realize the high efficiency and yielding of the working face.

通过对综采放顶煤工作面采煤机外喷雾、液压支架喷雾、转载点喷雾和风流净化水幕的联合改造，有效地降低了工作面粉尘含量，改善了工人作业环境，其对于实现工作面高产高效具有重要的指导意义。

Water pump station is mainly used in the mist spray and aspirating of coal cutter.It is a main part of the aspirating system of the coal face.

喷雾泵站主要应用于采煤机的喷雾除尘，是采煤工作面喷雾系统的主要组成部分。

In this paper, different coal face 3801 in a mine gas emission time is based on gray theory of gas emission prediction method, a mine gas emission in GM (1, 1) prediction model made its prediction of gas emission, by making the residual test, the results show that the prediction accuracy can be predicted.

本文以某矿3801采煤工作面不同时间段瓦斯涌出量为依据，运用灰色理论提出了瓦斯涌出量的预测方法，建立了矿井瓦斯涌出量的GM(1 ，1)预测模型，并对其进行了瓦斯涌出量的预测，通过进行残差检验，结果表明预测精度高，可以进行预测。

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。

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。

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。

Emulsion in coal mine to play a very important role, as the hydraulic mining machinery working media, particularly mine coal face, as hydraulic and hydraulic prop of the working media in the coal mine has been widely used mine support equipment known as the blood.

乳化液在煤矿生产中发挥着十分重要的作用，作为煤机产品液压传动的工作介质，尤其是作为煤矿采煤工作面液压支架和单体液压支柱的工作介质在煤矿井下得到了广泛的应用，被称之为煤矿支护设备的血液。

Museum's permanent exhibition -"simulated mine", its scale and rich in content, similar museums in the world is rare, he brought together the scientific, intellectual, interesting as one, the application of high and new technology and the arts each other The combination of modern means to create a display of real-borne Lane, the ancient manual mining, modern coal mining and blasting hole heading face, modern mechanized mining and geological structure as well as the heading face eight landscape.

博物馆永久的陈列——《模拟矿井》，其规模之大，内容之丰富，在世界同类博物馆中是少见的，他集合了科学性，知识性，趣味性为一体，应用了高新技术和艺术相互结合的现代展示手段来营造出逼真的媒巷，古代手工采煤，近代打眼放炮采煤和掘进工作面，现代综合机械化采煤和掘进工作面以及地质构造等八个景观。

This paper discusses design and realizable methods of remote test output interface from logical design angle.

本文从逻辑设计的角度讨论遥测输出接口的设计及实现方法。

This also 星体投射plies to buildings, structures and geological features.

这也适用于建筑物和地质特征。
