working face pressure的意思|示意

Introduction: now working pressure is more and more big, the white-collar workers face computer for a long period of time, if not to exercise, will inevitably lead to shoulder pain.

简介：现在的工作压力越来越大，使得白领们长时间的面对电脑，如果不加以运动，难免会导致肩膀酸痛。

Finally, the coal-rock mass in the arch angle and apex is slided, and causes the distortion of local rock pressure, even induces dynamic hazards around working face.

拱角与拱顶煤岩滑落失稳，造成工作面局部压力畸变并诱发动力学灾害。

An example provided in the case of wind is increased, which shows the dynamical balance feature between the air pressure in working face and gas pressure in the goaf.

给出增大风量后瓦斯分布的算例，由此反映出工作面风压与采空区内部瓦斯压力的动态平衡性。

According to the fieldwork experimentation, after adopting the high-pressure water injection technology, the width of the stress-relaxed zone at the front of the working face increases form 2.

现场试验结果表明：采取高压注水工艺后，工作面前方煤体卸压带宽度由2。

The testing results of working face coal samples and roof impact tendency indicated that the coal seam belongs to high impact tendency and has pressure bumping possibility.

工作面煤样和顶板冲击倾向性测试结果表明，该煤层属于高冲击倾向性煤层，具有发生冲击矿压的能力。

Thus it can been seen that enhancing the top monitoring during the period of the pressure change of working face has important practical meaning to security in coal mine.

由此可见，工作面来压期间加强顶板监控对煤矿安全生产具有重要的现实意义。
