采空区

I guess Gob smacked is appropriate, isn't it, Jack?

& &我猜想轰出采空区是适当的，是不是，杰克？

Study on the field stability at the mine abandoned stopes is a key step whether a construction can proceed or not.

煤矿废弃采空区场地稳定性研究是决定能否进行建筑的关键步骤。

Abandoned stopes; construction field; stability; evaluation

Since recent years, water penetration from gob of abondaned mines became a significant feature of water inrush in coal mines, threating serousely safe production in coal mines.

近年来，老窑采空区透水成为煤矿突水的显著特点之一，给煤矿的安全生产带来极大的威胁。

By the measures such as measuring the risk tendency of underground pressure eruption, evaluating risk index of underground pressure eruption, observing electromagnetic radiation, water injection in coal seam, long drill hole blasting, roof broken in gob area etc., realized safe coal production.

近年来鹤岗矿业集团公司的南部5个煤矿相继发生冲击地压现象，且造成不同程度的财产损失，通过采用冲击危险倾向性测试、冲击危险指数评估、电磁辐射观测方法，采用煤体注水、深孔爆破、采空区断顶等解危手段，实现了煤矿的安全生产。

In this paper, borrowing ideas from the research method of the spontaneous combustion mathematical model of goaf, applying to the hydrodynamic theory of porous medium, the spontaneous combustion mathematical model of coal gangue dump is set up.

本文借鉴了采空区自然发火数学模型的研究方法，以多孔介质流体动力学理论为指导，建立了煤矸石山自然发火数学模型，从数学上描述了矸石山自燃的动态演变过程，为自燃矸石山的防治措施提供了理论依据。

In this paper, borrowing ideas from the research method of the spontaneous combustion mathematical model of goaf, applying to the hydrodynamic theory of porous medium, the spontaneous combustion mathematical model of coal gangue dump is set up. From the mathematics, the dynamic evolvement process is described for the spontaneous combustion of coal gangue dump.

The stability of the goafs of Liangshi gypsum deposit is mainly influenced by the small thickness,water-absorption and low strengths of compression and shear of the upper walls of the orebodies;and by the clearages and bedding ;as well as the undergraound water activity and irregular mining.

两市镇缓倾斜石膏矿床采空区稳定性的影响因素，主要有矿体顶板硬壳——青膏层的厚度薄，易吸水软化，抗压抗剪强度低；区内局部节理发育、层理密集；地下水活动以及开采不规范等。

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。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
