Study on the key bed theory of roof supporting in stope
采場支撐頂板關鍵層理論的研究The thickness varies according to the half - apex angle, and the forming limit half - apex angle is the key which nc incremental sheet metal parts forming process succeeds, it relates to the material and thickness of the sheet metal
變形區厚度的變化與成形半頂角有關，其中，成形極限半頂角是數控漸進成形能否成功的關鍵，它不僅與材料有關，而且與板料厚度有關。Software design includes the following : firstly stb part - bottom drive : including front - end drive, flash drive, the receiving software of the front board key - press and remote control signal
機頂盒部分底層驅動程序，包括：前端驅動、 flash驅動、前面板按鍵接收軟體和遙控信號接收軟體等。In accordance with the occurrence behavior of roof strata and the fracture characteristics of key stratum in shallow seam longwall mining, studied post - buckling behavior of roof key stratum in the process of mining by using initial post - buckling theory, which derived a critical load and a breaking span of the main roof during the first weighting, determined the final subsidence and the maximum rotation angle for broken key stratum, and presented an application with the example of daliuta 1203 face
摘要根據淺埋煤層頂板巖層的賦存特點和長壁開采時關鍵層的變形破斷特徵，應用初始后屈曲理論探討了開采過程中頂板關鍵層的后屈曲性態，得出了老頂初次來壓時頂板的臨界載荷和破斷步距，確定了頂板破斷后的極限下沉量和回轉角，並以神東礦區大柳塔1203工作面為例給出了工程實例。Because the loader and the moduls of elasticity exists part difference in key stratum and combinatorial key stratum, and the formulae of calculating the roof weighting step has difference, so there must be existing big error if we use the formulae of key stratum to calculate the shallow coal seam ' s weighting parameter
大柳塔1203工作面按照關鍵層計算得出的頂板來壓步距與實際相差很大，而按照組合關鍵層計算得出的頂板來壓步距與實際基本吻合。It is pointed that the thick unconsolidated layers above roof have effect on post - buckling behaviors of key stratum, the equilibrium path of roof is unstable from breaking to final subsidence
研究發現，頂板上覆厚鬆散沙層對關鍵層的后屈曲性態有影響；頂板從破斷至極限下沉其平衡路徑不穩定。The keys to its success - this is almost certainly the greenest office building in the asia - pacific - are not the solar panels or the wind turbines on the roof but the " passive " systems that enable the building to use the natural climate rather than fight it
這座樓幾乎可以肯定是亞太地區最環保的辦公樓，它成功的關鍵並非房頂上的太陽能電池板或風輪機，而是"被動"系統- -讓這座大樓能利用而非對抗自然氣候。The paper discussed the basic structure and functions of monitoring system of plank pressure based on embedded system underground, and introduced the key techniques to realize this system
摘要討論了基於嵌入式系統的井下頂板壓力監測系統的基本結構和所實現的功能，詳細介紹了實現該系統的關鍵技術。In recent years, during the detection of the established reinforced concrete or the prestressed concrete box girder bridges etc. the large structures, we can find that the concrete in particular structural positions such as the anchorage zones of prestressed reinforcement with dense reinforcement, the prestressed pipe in which the space of reinforcement or the thickness of concrete cover is small, the top and bottom flange of box girder and so on has brought great difficulty to concrete construction because of the small size and densely - packed reinforcement
對于變截面t梁、工字梁、箱梁等常見結構，截面形式復雜，一些部位尺寸較小且密集配筋，如梁頂板，梁底板，預應力管道間，混凝土不可避免的造成不密實導致耐久性降低，而這些問題往往為設計者所忽略。對于新建橋梁混凝土的密實度問題，尤其是新建橋梁關鍵部位的混凝土密實度和耐久性問題，人們研究和關心的較少，這也為橋梁的質量監督控制和使用壽命埋下了隱患。分享友人
